A bat and ball approach one another each with the same speed of 1.50 m/s, collide. Determine the speed of the ball after the collision. (Assume the mass of the bat is much larger than the mass of the ball and that this is an elastic collision with no rotational motion).
Two hydrogen atoms collide head on. The collision brings both atoms to a halt. Immediately after the collision, both atoms emit a 121.6 nm photon. What was the speed of each atom just before the collision?
