A baseball of mass m1 = 0.46 kg is thrown at a concrete block m2 = 8.25 kg. The block has a coefficient of static friction of μs = 0.81 between it and the floor. The ball is in contact with the block for t = 0.165 s while it collides elastically.

Question

m1 = 0.46 kg
m2 = 8.25 kg
μs = 0.81
t = 0.165 s

Part (a) Write an expression for the minimum velocity the ball must have, vmin, to make the block move.

Part (b) What is the velocity in m/s?
