Why is it that a cat that accidentally falls from a 50-story building hits a safety net below with the same speed as if it fell from a 20-story building?

A 0.7 ball falls down and hits the floor at a speed of 15 m/s. The ball then bounces back up at aspeed of 12 m/s. If the ball was in contact with the floor for 0.06 s, what was the average force from the floor on the ball?

a 925-kg pick up decelerates to rest from a speed of 97.5 km/h in a distance 125 m. Suppose the pick up is initially traveling in the positive direction. suppose instead of breaking that the pick up hits a concrete abutment at full speed is brought up to a stop at 2.0 m. Calculate the force in newtons exerted on the pickup in this case.

Ignoring air drag, the rocket will travel a distance of m further before reaching its maximum height. (Record your answer in the numerical-response section below.) Your answer: 0000 11. A toy snowmobile has a mass of 21.0 kg and a velocity of 94.0 m/s directed at 10.0° N of E. The component of the snowmobile's momentum in the North direction is kg-m/s. (Record your answer in the numerical-response section below.) Your answer: 0000 Use the following information to answer the next three questions Object 1 with a mass of 4.80 kg, moving right at a speed of 8.60 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.70 kg moving left at a speed of 10.8 m/s. After the collision, the Object 1 is moving left at 2.20 m/s. 12. The final speed of object 2 would be m/s. Answer to 3 sig digs. (Record your answer in…

Two ice skaters stand together as illustrated in Figure (a). They "push off" and travel directly away from each other, the boy with a velocity of v = +0.42 m/s. If the boy weighs 718 N and the girl 450 N, what is the girl's velocity after they push off? (Consider the ice to be frictionless.)

A constant horizontal force F = 200 N is applied for a time 0.1 s by a kick to a soccer ball of mass m=0.4 kg. If the ball was initially traveling toward the player at 20 m/s, what is the speed as it leaves her foot traveling in the opposite direction?  Choose the correct answer. 50 m/s 20 m/s 10 m/s 30 m/s 70 m/s

A high-speed photograph of a club hitting a golf ball is shown in the figure below. The club was in contact with a ball, initially at rest, for about 0.0024 s. If the ball has a mass of 55 g and leaves the head of the club with a speed of 1.9 x 102 ft/s, find the average force (in kN) exerted on the ball by the club. kN
