An open train car, with a mass of 2130 kg, coasts along a horizontal track at the speed 2.99 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 3.31 s at the rate of 495 kg/s. What is the car's speed vf after the loading is completed? Ignore rolling friction. Uf = m/s

On the set of a new Hollywood movie, a 84.6-kg stunt actor (Max Payne) is tossed straight out of a helicopter hovering (stationary) at a height of 55.3 meters. The stunt actor is thrown from the helicopter at a speed of 4.56 m/s, eventually landing in the water below. Determine the stunt actor's impact speed and assume negligible air resistance. You can use the approximation that g = 10 m/s2. Answer: _________ m/s (round to the nearest hundredth)
During a squash game, a player hits the ball, of 24 g, which is moving toward him horizontally at 150 km/h. The impact between the racket and the ball lasts 1.2 ms and the ball leaves with an identical speed but in the opposite direction as the initial velocity. The ball then hits the wall in front, 8 m away and 18 cm below the height of the hit. What is the average force acting on the ball during the impact?

A tennis ball is flying eastward towards a wall with a speed of 33.7 m/s. After bouncing against the wall, it's flying westward with a speed of 21.9 m/s. If the mass of the ball is 0.1 kg, and the time the tennis ball is in contact with the wall is 0.032 s, what is the magnitude of the force in N the ball exerts on the wall?
A 6-g bullet is shot into a 2.1-kg block of wood, where it becomes embedded. The block is initially at rest and the bullet has an initial velocity of 400 m/s. The block then travels 1.2 m horizontally. What is the coefficient of kinetic friction between the block and the surface?
A block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2? Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
A 14.4-g wad of sticky clay is hurled horizontally at a 71-g wooden block initially at rest on a horizontal surface. The clay sticks to the block.
