Question

Consider the following 3 pieces of the motion for a block that is initially at rest on a floor. (1) The block's velocity is zero at the instant it is given a quick push by a hand. (2) The hand does not touch the block after the quick push. The block slides across the floor, gradually slows down, then comes to rest. In (3), the block is at rest. The next series of questions will pertain to these cases.

In (2), after the hand has let go but while the block moves, what is the direction of the net force on the block?
