A train car of mass mị rolls down a hill, starting from rest from a height h; above the valley floor. At the bottom of the valley, car m1 bumps into a second car of mass m2 that has been standing there. The two cars lock to each other and jointly start climbing up the hill on the other side of valley, until they momentarily come to rest at a height hf above the valley floor. Assuming you can neglect friction, what is the ratio between m2 and m1 if hf = h;/9? Check: For hf = hi/16 you should find m2 = 3m1. Hint: Analyze this problem in three stages. The middle (second) stage will be the collision of the two train cars; from right before to right after they collide.

A 4.50 kg box sits halfway up a 12.0 m long ramp that is inclined at an angle of 20.00. 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 17.0 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 0.100. Where, from the bottom of the ramp, do they come to rest?
A S B 3.766 h Sphere A with mass 1.8 kg is dropped from rest h = 9 m above the smooth ramp-shaped block (mB 0 = 30°). The block is initially at rest on a smooth horizontal surface. ? x 0% 9 0 If the coefficient of restitution for the impact is e = 0.8, find how far the block has moved 4 seconds after the impact. Neglect the size of the sphere and assume the block remains in constant contact with the supporting surface. m = 12 kg,
In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal. At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?
7.56 A 1500-kg rocket is Figure P7.56 to be launched with an initial upward speed of 50.0 m/s. In order to assist its engines, the engineers will start it from rest on a ramp that rises 53° above the horizon- tal (Fig. P7.56). At the bot- tom, the ramp turns upward and launches the rocket ver- tically. The engines provide a constant forward thrust of 2000 N, and friction with the ramp surface is a constant 500 N. How far from the base of the ramp should the rocket start, as measured along the surface of the ramp? Rocket starts here. 53% Rocket is launched upward.
A cat of 20 kg mass is running at 8.0 m/s toward a stationary skateboard with a mass of 2 kg. The cat jumps on the skateboard once it reaches it. The skateboard and cat roll forward together without friction until they reach a ramp 30◦ above horizontal. If the coefficient of kinetic friction between the skateboard and the ramp is µk =0.3, what is the maximum height the skateboard can reach?
A tourist is driving across Canada. They are currently in the rolling planes of Saskatchewan. They reach the peak of a hill. At the peak, they are travelling at 50 [ km/h]. They continue down the hill to a trough. At the bottom of the trough, they are driving at 100 [km/h]. The magnitude of the acceleration of the vehicle's mass center is the same at the peak and the trough. The vehicles mass center is 0.6 [m] from the road. It takes 10 seconds to travel from point A to B. Determine: a) The radius of curvature, PB, of the section of the road with the trough. Use the problem diagram below. 0.6 m Vrough PR Radius of Curvature at B V peak 40 m Radius of curvature at A
A bullet (m = 0.027 kg) is fired with a speed of 92.00 m/s and hits a block (M = 2.20 kg) supported by two light strings, stopping quickly. Find the height h to which the block rises. Find the angle through which the block rises, if the strings are 0.26 m long.
