A 20.0 kg ball with velocity of 20.0 m/s East strikes a 2.00 kg ball that is initially at rest. After collision, the velocity of the 20.0 kg ball has decreased to 15 m/s. Find the final velocity of the 2.00 kg ball.
2. An 8.00 kg ball traveling at 4.00 m/s strikes another ball M2. After collision, M1 is traveling in the same direction but at only 3.00 m/s, and M2 is traveling at 4.00 m/s. Find the mass of M2.
A 4.00 kg ball with a velocity of 4.00 m/s East, overtakes a 2.00 kg ball traveling at 2.00 m/s East. If the final velocity of the 4.00 kg ball is 3.00 m/s, find the final velocity of the 2.00 kg ball.
A 10.00 kg ball traveling at +6.00 m/s overtakes a 5.00 kg ball traveling at +4.00 m/s. If the 10.0 kg ball slows down to +3.00 m/s after the collision, find the final velocity of the 5.00 kg ball.
A 20.0 kg ball with V = 5.00 m/s East strikes a 2.00 kg ball with velocity 10.0 m/s West. If the final speed of the 20.0 kg ball is 3.00 m/s East, what is the final velocity of the other ball?
A 6.00 kg ball traveling East at 2.00 m/s strikes ball B of mass 2.00 kg at rest. If they stick together after collision, what is their final velocity?
7. When the 80.0 kg football player, who is standing on a frictionless surface, catches a 4 kg football moving at 30 m/s, what will be his final velocity?
A 3.00 kg mass moving at 2.00 m/s North strikes a 1.00 kg mass at rest. After the collision, the 3.00 kg mass moves at 1.00 m/s at 60 West of North. Find the velocity and direction of the 1.00 kg mass. Assume the collision is perfectly elastic.
Ball A, of mass 4.00 kg and heading North at 2.00 m/s, strikes a 2.00 kg Ball B which is at rest. After collision, Ball A is traveling at 1.50 m/s at 55 North of East. Find the speed and direction of Ball B.
