(C) The mass of each ball is $m = 250 \ g = 0.25 \ kg$.The initial velocity of the first ball is $v_i = 16 \ m \ s^{-1}$.After the collision,the ball rebounds with the same speed in the opposite direction,so the final velocity is $v_f = -16 \ m \ s^{-1}$.Impulse is defined as the change in momentum: $J = \Delta p = m(v_f - v_i)$.Substituting the values: $J = 0.25 \ kg 	imes (-16 \ m \ s^{-1} - 16 \ m \ s^{-1})$.$J = 0.25 \ kg 	imes (-32 \ m \ s^{-1}) = -8 \ kg \ m \ s^{-1}$.The magnitude of the impulse imparted is $|J| = 8 \ kg \ m \ s^{-1}$.

Two balls each of mass $250 \ g$ moving in opposite directions each with a speed $16 \ m \ s^{-1}$ collide and rebound with the same speeds. The impulse imparted to one ball due to the other is
