### Physics Problem: Calculating Falling Speed Using Pulley System---Wayne, Daryl, Katy Cat, Bonny, and Squirrely Dan are trying to finish their chores on the farm. They have to bring down a couple of bags of cattle feed from the 2nd floor of their barn, to the bottom. To do this, they will use a disc pulley to lower the two bags of cattle feed down. As a counterweight, they will use their friend Stewart. Stewart will start on the ground with the rope attached to him, and since Stewart has a lower mass than the two bags of cattle feed, when they put the cattle feed over the edge on the 2nd floor, the cattle feed will fall down, and Stewart will be raised up. Using the givens below, calculate how fast the bags of cattle feed will be falling the instant before they hit the ground.#### Given Data:1. **Mass of Stewart:** 55 Kg2. **Mass of the two bags of cattle feed:** 70 Kg3. **Height of the 2nd floor of the barn:** 2.5m4. **Radius of the disc pulley:** 0.75m5. **Mass of the disc pulley:** 4 Kg6. **Acceleration of Gravity:** 10 m/s²#### Diagram Explanation:Imagine a simple pulley setup where the rope attached to Stewart on one side of the disc pulley and two bags of cattle feed on the other side. As the cattle feed bags descend, Stewart ascends simultaneously since they are connected through the pulley system.---**Calculation Steps:**1. Analyze the forces acting on both Stewart and the cattle feed bags.2. Incorporate the disc pulley's rotational inertia.3. Apply Newton's Laws and the principles of energy conservation to derive the final velocity.Explore these principles and calculations further to understand how mechanical systems like pulleys can make work easier and more efficient on a farm.---

The tension is growing!Context At your summer job, your supervisor wants to test your physics skills. A new winch (a cable driven by a motor) is to be used to hoist loads up an inclined ramp. Your supervisor is worried about the packages arriving too quickly at the top of the ramp. Constraints The inclined ramp is made up of small cylinders that are free to rotate: there is no friction between the ramp and the load.The angle theta of the ramp from the horizontal is known.The winch cable exerts a known force.The cable is oriented at an angle a from the horizontal.The charge, initially immobile, has a known mass.The length of the ramp is known. Schematization Draw a diagram of the object that interests us. Draw your x and y axes. Draw and name each force experienced by the object that interests us. Modelization Build a model to calculate the final speed of the load as it arrives at the top of the ramp, given the known parameters. Then test your model with the following values: Ramp…
The figure shows a block of mass m resting on a 20o slope. The block has coefficients of friction us=0.64 and uk=0.54 with the surface of the slope. It is connected using a very light string over an ideal pulley to a hanging block of mass 2.0 kg. The string above the slope pulls parallel to the surface. What is the minimum mass m so the system will remain at rest when it is released from rest?
A new Dutchman Day activity allows people to leap from the top of the Humanities building onto a giant pillow on the ground below. The distance between the top of the Humanities building and the top of the pillow is 9.34 m. The giant pillow compresses 0.781 m as it brings a 60.7-kg person to rest. Find the magnitude of the force (in N) exerted by the giant pillow on the person. You may assume this force is constant during the time that the person is in contact with the pillow.
In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal as shown in (Figure 1). At the very top of his arc, a 70 kg vaulter is moving at 2.9 m/s and is 5.5 m from the bottom end of the pole. What is the magnitude of the vertical force that the pole exerts on the vaulter? Express your answer with the appropriate units.
A 686 N park ranger uses a basket and a rope-pulley system to transport an injured sea turtle up to a plateau, as shown in the figure. The sea turtle and basket together have a mass of 50.0 kg. The ranger holds firmly onto the rope and walks away from the cliff, speeding up at a steady rate of 0.300 m/2 2. He thereby causes the basket (and the turtle) to accelerate straight upwards at the same rate. Assume that the rope has negligible weight and that the pulley is ideal, having no friction in its bearing. Also assume that as the ranger trudges along, his feet do not slip on the ground. +x 26. The tension in the rope is equal to A. 490 N. B. 686 N. C. 475 N. D. 505 N. E. 196 N. 27. The frictional force which the ground exerts on the ranger's feet has a magnitude of C. 526 N. A. 490 N.

A 2.50 kg box sits halfway up a 16.0 m long ramp that is inclined at an angle of 16.00. You shove a second box, of mass 1.50 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 20.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.200. Where, from the bottom of the ramp, do they come to rest?

Which answer below is closest to the magnitude of the normal force that the idealized in-run exerts on the 60-kg skier? The 2010 Olympic ski jumping competition was held at Whistler Mountain near Vancouver. During a jump, a skier starts near the top of the in-run, the part down which the skier glides at increasing speed before the jump. The Whistler in-run is 116 m long and for the first part is tilted down at about 35° below the horizontal. There is then a curve that transitions into a takeoff ramp, which is tilted 11° below the horizontal. The skier flies off this ramp at high speed, body tilted forward and skis separated (Figure 4.15). This position exposes a large surface area to the air, which creates lift, extends the time of the jump, and allows the jumper to travel farther. In addition, the skier pushes off the exit ramp of the in-run to get a vertical component of velocity when leaving the ramp. The skier lands 125 m or more from the end of the in-run. The landing surface has…

Try again. A 4.6 kg body is at rest on a frictionless horizontal air track when a constant horizontal force F acting in the positive direction of an x axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in the figure. The force F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals. How much work is done on the body by the applied force F between t = 0 and t = 1.8 s? 0.5s -1.0 s 1.5s 2.0 s 0.2 0.4 0.6 0.8 x (m) Number To.8 Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work SHOW HINT LINK TO TEXT LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE to search 10:33 PM ENG 4/4/2021 ASUS 13) 16 17 1ghome 3 4 R U F G ト

Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B is full. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is µs. The speed of the turntable is gradually increased. Describe what will happen. Include which container will fall off first or if they will fall off at the same time.
Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?
