What does the magnitude of the net force on the cart need to be? What does the magnitude of the cart's acceleration need to be? m/s? At what incline angle (0) does the ramp need to be slanted? What will be the maximum speed of the cart? m/s

A basketball player jumps straight up for a ball. To do this, he lowers his body 0.300 m and then accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry him 0.900 m above the floor. (a) Calculate his velocity when he leaves the floor. (b) Calculate his acceleration while he is straightening his legs. He goes from zero to the velocity found in (a) in a distance of 0.300 m. (c) Calculate the force he exerts on the floor to do this, given that his mass is 110.0 kg.
Two boxes with masses m1 = 4.00 kg and m2 = 10.0 kg are attached by a massless cord passing over a frictionless pulley as shown in Figure P5.79. The incline is frictionless, and = 30.0. a. Draw a free-body diagram for each of the boxes. b. What is the magnitude of the acceleration of the boxes? c. What is the tension in the cord connecting the boxes? d. What is the speed of each of the boxes 3.00 s after the system is released from rest? FIGURE P5.79
A little toy car is powered by a CO2 cartridge that produces a thrust force according to the following function: Fthrust(t) = 6.0N e-0.2t. The car also has a friction coefficient of 0.05 due to the wheels and bearings. If the car's mass is 1.2kg, and the car travels in the +x direction, what will it's acceleration function look like as a function of time? If it starts from rest, what will vx(t) be? How fast will the car be going after 3.0s? What maximum speed will be reached by the car?
A basketball player jumps straight up for a ball. To do this, he lowers his body 0.270 m and then accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry him 0.940 m above the floor.
Two blocks of mass ? and 2? rest on a rough incline plane with coefficient of kineticfriction ??. The two blocks are connected to a cable with tension ?1, and the block of mass ? isconnected to a ball of mass ? by a cord over a lightweight, frictionless pulley with tension ?2, asshown below. When the system is released from rest, the ball of mass ? accelerates downward,and the two blocks accelerate up the incline. You may ignore the mass of each cord.
A car has a mass of 1750 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 6500 N. If the car is moving at 22 m/s, what is the shortest distance in which the car can stop safely?
A skier (68 kg) is on a ramp that is inclined at an angle of 20 degrees. The height of the ramp is 57 feet. The skier launches herself off the ramp with an initial velocity of 15 m/s. How far does the skier travel horizontally before landing on the snow? How long is the skier airborne? What forces are we neglecting here? What force is constant?
As a fish jumps vertically out of the water, assume thatonly two significant forces act on it: an upward force F exertedby the tail fin and the downward force due to gravity. A recordChinook salmon has a length of 1.50 m and a mass of 61.0 kg.If this fish is moving upward at 3.00 m/s as its head first breaksthe surface and has an upward speed of 6.00 m/s after twothirdsof its length has left the surface, assume constant accelerationand determine (a) the salmon’s acceleration and (b)the magnitude of the force F during this interval.
A 5kg block is pulled westward across a frictionless horizontal surface by a 30 N force applied at 87° angle above the horizontal? What is the block's acceleration? What is the normal force?
In a slow-pitch softball game, a 0.2 kg softball crosses the plate at 15 m/s at an angle of 45° below the horizontal. The batter hits the ball toward center field, giving it a velocity of 40 m/s at 30° above the horizontal. a) Determine the impluse delivered to the ball. b) If the force on the ball increases linearly for 4 ms, holds constant for 20 ms, and then dcreases linearly to zero in another 4 ms, what is the maxium force on the ball ?
While standing on a frozen lake (µf = 0) you throw a rock with a mass of 2.25 kg at vb = 12.0 m/s. Thedistance between you and the rock when it lands is 15.2 m. If your mass is 32.5 kg and you take the initialheight of the rock to be zero, at what angle did you throw the rock? Also, what is your velocity after throwing the rock?
A motorcycle daredevil plans to ride up a 2.00 m high 26.0° ramp, sail across a 10-m-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as starts up the ramp. He is going 14.9 m/s at that instant, and the rolling friction of his rubber tires is not negligible. Assuming that the local acceleration due to gravity is -9.80 m/s2, calculate the landing point (in m) relative to the 10.0 m edge of the pool. (-1.0 m means he was 1.0 m short and in the pool, +1.0 m means he landed 1.0 m past the edge). The coefficient of rolling friction for rubber on ramp is 0.02.
