Suppose a 10 kg block is set on a frictionless surface of infinite length. I then apply a constant force in the form of a constant push such that the block accelerates at a constant rate of 1 m/s^2. The force I apply will be F=ma= 10kg*1m/s^2= 10N. Suppose I apply this force for 10 seconds. Then at=v = (1m/s^2)(10s)= 10m/s. I am applying 10N of force for the duration of the 10 second push. So the block is experiencing a net force of 10N. I stop pushing the block at exactly 10 seconds so that the block is traveling at a constant velocity of 10m/s. Now, suppose there is a second block of 100kg on the frictionless surface set at rest directly in the path of the block in motion. When the moving block hits the stationary block, what forces occur? All I know I that the force I applied to the block was 10N and the net force on the block after 10 seconds was 0N. How does force fit into the scenario upon impact and after impact?
