constant speed

A block on a rough horizontal surface is moving to the left with constant speed under two horizontal forces 2 N and 12 N indicated as shown. If the force of 12 N is suddenly removed, what is the net force acting on the block at that instant ?

Two  particles P and Q start from the same position and travel along the same straight line. The figure shows the velocity-time (v-t) graph for P and Q. Which of the following descriptions about their motion is/are correct ?

(1) At t = 1 s, P changes its direction of motion.(2) At t = 2 s, the separation between P and Q is 4

m.(3) At t = 4 s, P and Q meet each other.
