A ball and bat, approaching one another each with the same speed of 1.3 m/s collide. Find the speed of the ball after the collision. (Assume the mass of the bat is much much larger than the mass of the ball and that this is an elastic collision with no rotational motion).
The specific heat capacity of the material use to make the block is C resolve the temperature rise that results from the collision in terms of C and the other given quantities.( suppose that no energy is transferred to the track or the surrounding..
