Question

A baseball of mass m1 = 0.26 kg is thrown at a concrete block m2 = 7.25 kg. The block has a coefficient of static friction of μs = 0.77 between it and the floor. The ball is in contact with the block for t = 0.105 s while it collides elastically. The force of interaction between the block and the ball is constant for the duration of their collision.
Randomized Variables
m1 = 0.26 kg
m2 = 7.25 kg
μs = 0.77
t = 0.105 s

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