Vedclass · Answer

(A) Impulse is defined as the change in momentum of an object.Let the mass of each ball be $m = 0.06 \,kg$.The initial velocity of the first ball is $v_i = 4 \,m/s$ and the second ball is $-4 \,m/s$.After the collision,the balls rebound with the same speed,so the final velocity of the first ball is $v_f = -4 \,m/s$ and the second ball is $4 \,m/s$.The change in momentum for one ball is $\Delta p = m(v_f - v_i)$.$\Delta p = 0.06 	imes (-4 - 4) = 0.06 	imes (-8) = -0.48 \,kg \cdot m/s$.The magnitude of the impulse imparted to each ball is $|\Delta p| = 0.48 \,kg \cdot m/s$.

If two balls each of mass $0.06 \,kg$ moving in opposite directions with speed $4 \,m/s$ collide and rebound with the same speed,then the impulse imparted to each ball due to the other is ........... $kg \cdot m/s$.
