Chapter 7, Problem 14MCQ

Two clay balls are moving toward each other. The balls have equal kinetic energies $\left(K_1=K2\right),$ but ball 1, which is coming from the left, is moving faster than ball $2(v_1>V2).$

Which answer correctly explains how the balls will move after a totally inelastic collision?

The balls will not move because $K_1=K2$ before the collision.

The balls will move to the left because $p_2>P_1$ before the collision.

The balls will move to the right because $v_1>V2$ before the collision.

We cannot predict how the balls will move after the collision.
