Problem 1. Tony crashes into Nancy while they are practicing their figure skating routines. Tonya’s mass is 70kg and Nancy’s mass is 55kg. Just before the collision occurs, Tonya’s velocity is 5.5m/s and Nancy’s velocity is 7m/s in the opposite direction. During the collision, Tonya exerts an average force of 977N against Nancy. A. How big is the average force Nancy exerts against Tonya during the collision? B. If this is the only horizontal force acting on each skater during the collision, what average horizontal acceleration does each skater experience during the collision? C. If the collision is perfectly inelastic, how fast and in what direction will Tonya and Nancy be moving immediately after the collision?

A racquet ball with mass m = 0.244 kg is moving toward the wall at v = 15 m/s and at an angle of θ = 27° with respect to the horizontal. The ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. The ball is in contact with the wall for t = 0.067 s. 1)What is the magnitude of the change in momentum of the racquet...

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.

please help!
The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...
