A block of mass M1=2.9 kg rests on top of a second block of mass2=5.5 kg, and the second block sits on a surface that is so slippery that the friction can be assumed to be zero.

Question:
(a) if the coefficient of static friction between the blocks is 0.21, how much force can be applied to the top block without the blocks slipping apart?

(b) how much force can be applied to the bottom block for the same result?
