5 You have two objects with the same mass and they are going to collide with respect to each other. Estimate the ratio between the total kinetic energy associated with the two objects before and after the collision. Assume that the collision was a perfectly inelastic collision and that one of the two objects was moving with a certain velocity and the other was at rest before the collision.

Mass A (3 kg) and Mass B (1 kg) collide head‐on on a frictionless surface.  A was initially moving to the right at 0.2 m/s, while B was moving at 0.4 m/s to the left.  The collision is completely elastic. a) Find the velocity (magnitude and direction) for each mass after the collision.  Treat this as a one dimensional problem. b) Find the change in momentum for each mass.  Compare. c) Find the change in kinetic energy for each mass.  Compare.

a) Two objects with the same mass move toward each other with the same speed and experience a head-on elastic collision (angle = 180o). Will their final velocities be the same? Why? b)Two objects moving toward each other (angle = 180o) with different momentums produce an inelastic collision. In what condition will both objects move to the left after the collision.

Three billiard balls, all having a mass of 0.170 kg, collide on a horizontal, table. Prior to the collision the red ball is traveling to the right at 1.50 m/s, the green ball is traveling ‘upwards and left’ (45o) at 1.20 m/s, and the yellow ball is traveling ‘downwards’ (90o) towards the crash site at 2.0 m/s. After the collision, both the red and yellow balls are stopped, and the green ball goes off at some velocity. Draw the before...

A ball with mass M = 5 kg is moving with speed V=10 m/s and collides with another ball with mass m = 2.5 kg which is initially stationary. There is no other force such as gravity acting on the two balls. After the collision, both balls move at angle θ=30 degrees relative to initial direction of motion of the ball with mass M = 5 kg. a) What are the speeds of the two balls after the collision? b)...
