Question

A baseball of mass m1 = 0.45 kg is thrown at a concrete block m2 = 6.75 kg. The block has a coefficient of static friction of μs = 0.86 between it and the floor. The ball is in contact with the block for t = 0.185 s while it collides elastically. The force of interaction between the block and the ball is constant for the duration of their collision.

Randomized Variablesm1 = 0.45 kg
m2 = 6.75 kg
μs = 0.86
t = 0.185 s

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

What is the velocity in m/s?
