A 0.5 kg ball bounces off a wall. The magnitude of the velocity is 4 m/s both before it hits the wall and right after. If the ball was in contact with the wall for 5 m/s, what was the average force exerted on the ball? A. -800 B. 800 C. -8x10^-4 D. 8x10^-4
4) A ball with a mass of 0.15 kg has a velocity of 5 m/s. It strikes a wall perpendicularly and bounces off straight back with a velocity of 2 m/s. The ball underwent a change in momentum equal to (There is only one answer) (2p) A) 0.20 kg. m/s B) 1.20 kg. m/s C) 1.05 kg. m/s D) 6 kg. m/s E) 8.5 kg. m/s 5) A 2-kg mass moving with a velocity of 6 m/s collides elastically with...
A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3. A 2000 kg SUV traveling at 7 m/s south runs into the rear end of an 800 kg compact car sitting...
8) During a collision with a wall,the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball? A) 26.7 N B) 13.3 N C) 107N D) 40.0 N E) 16.7 N 10) A 5.0-m radius playground merry-go-round with a moment of inertia of 2000 kg.m2...
