Retarding frictional force, f, on a moving ball, is proportional to its velocity, V. Two identical balls roll down identical slopes (A and B) from different heights. Compare the retarding forces and the velocities of the balls at the bases of the slopes.

• f_A > f_B; V_A > V_B

• f_A > f_B; V_B > V_A

• f_B > f_A; V_B > V_A

• f_B > f_A; V_A > V_B

• their thickness remains unchanged, but their length increases.

• their thickness remains unchanged, but their width decreases.

• their thickness decreases, but the rest of the size remains unchanged.
