A block of mass 2.0kg rests on top of another block of mass 5.0kg. The lower block is attached to a spring of stiffness K=240N/m and slides along a frictionless surface. Friction between the two blocks holds them together. The coefficient of static friction is 0.50
(a) Draw diagram showing all the forces on each block?
(b) What is the maximum amplitude of oscillations possible such that the block stay together?
