Suppose you use an ideal pulley of the type shown in Figure 5.18(c) to support a car engine of mass 130 kg. What would the tension in the rope be?  N What force must the ceiling supply, assuming you pull straight up on the rope? The pulley system's mass is 5.00 kg.  N (upward)

a. Calculate the force (in N) needed to bring a 950 kg car to rest from a speed of 80.0 km/h in a distance of 110 m (a fairly typical distance for a non-panic stop).   b. Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a).   force in (b)/force in (a)=

As shown in figure, find that at what distance body A will attain a velocity of 3 m/s when starts from rest.Assume the coefficient of Friction as 0.2 and pulleys are frictionless and weightless.

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.

Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the Oyoy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 106.0 kg and is shaped like a cylinder of radius R = 0.835 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0830 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius = r Mass = M The FORMULA for the moment of Inertia: I = V(y=0)=? We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 77.5 kg is using the Oyoy and…

A 756 N person travels in his vehicle through a deep circular-shaped dip in the road. When the vehicle passes through the lowest point of the 50.0 m dip, the seat exerts an 1110 N force on the person. Determine the speed of the vehicle at this point.

A 325-g model boat facing east floats on a pond. The wind in its sail provides a force of 1.45 N that points 25 north of cast. The force on its keel is 0.613 N pointing south. The drag force of the water on the boat is 0.750 N toward the west. If the boat starts from rest and heads east, what is its final speed by after it travels for a distance of 4.15 m? Uy = -14.4 m/s

A 10N force is applied (pushed down) at a 37 degrees angle onto a Box at rest. The Box then reaches a speed of 30 m/s in 15 seconds along a frictionless surface. What is the mass of the Box in kg?
