Atwood machine question: (When M1 and M2 are equal) explain what happens when one side is pulled down and released (while still in motion)? Explain qualitatively what happens after releasing the mass. Do they continue moving? Do they speed up? Slow down? Explain this result. Use appropriate terminology (velocity, acceleration) to compare the motion of each set of washers.

A football of mass 500g approaches a players food at 4 m/s. The player kick it back along its original path, exerting a force of 45N opposite the direction of approaching ball. His foot is in contact with thr ball for 0.2s. Ignore the effect of friction. 1. Calculate the velocity at which the ball leaves the player's foot. 2. Calculate the change in momentum of the ball. 3. Use vector diagram to illustrate this change.
