A baseball of mass m1 = 0.32 kg is thrown at a concrete block m2 = 6.25 kg. The block has a coefficient of static friction of μs = 0.71 between it and the floor. The ball is in contact with the block for t = 0.195 s while it collides elastically.
What is the minimum velocity the ball must have to make the block move?

force to move block=mu*m2*g
force*time=massball(2v)
v=force*time/2*massball=
= mu*m2*g*t/2m1
force*time=massball(2v)
v=force*time/2*massball=
= mu*m2*g*t/2m1
