Explanation:
Two steel ball of equal diameter are connected by a rigid bar of negligible weight as shown and are dropped in the horizontal position from height h above the heavy steel and brass base plates. If the coefficient of restitution between the ball and steel base is 0.6 and that between the other ball and the brass base is 0.4. The angular velocity of the bar immediately after rebound is _______. Assume the two impacts are simultaneous.

For end A .6 V = u + l / 2 .ω & B .4 V = u – l / 2. ω Subtracting 2 V = ωl ω=2v/ l Now using [V2 = u2 + 2aS] V2 = 0 + 2 × 10 × .1 = 2Read more on Sarthaks.com - https://www.sarthaks.com/434343/steel-ball-equal-diameter-connected-rigid-negligible-weight-shown-dropped-the-horizontal
