A ball with original momentum +4.0 kg m/s hits a wall and bounces straight back without losing any kinetic energy. The change in momentum of the ball is?
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 0.1 kg ball hits a wall at right angles to the surface and bounces off. Before the collision, the ball’s velocity component perpendicular to the wall is vi,x = −8 m/s. After the collision, it is vf,x = +6m/s. What is ∆px, the change in the ball’s momentum perpendicular to the wall? A. −1.4kgm/s B. +1.4kgm/s C. +0.8kgm/s D. −0.6kgm/s E. −0.2kgm/s
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. 1) What is the magnitude of the initial momentum of the racquet...

A 4.0 kg object is moving at 5.0 m/s NORTH. It strikes a 6.0 kg object at rest. The objects have an elastic collision and move in the NORTH or SOUTH direction. The velocity of the 6.0 kg object after the collision is
A 2 kg ball moving at 4 m/s to the right collides with a 3.0 kg ball moving at 2.0 m/s to the left. A) What is the total momentum before the collision? B) After the collision, if the first ball now moves at 1.2 m/s to the left, what is the momentum of the second ball? C) Then, using your answer for B, find the velocity of the second ball after the collision. (right is + left is -)...
