Two blocks (m1= 10 kg and m2= 30 kg) in the figure oscillate on a frictionless (horizontal) surface with a
period of 1.5 s. The upper block (m1) just begins to slip when the amplitude is increased to 40 cm.
(a) With the maximum amplitude, what is the maximum acceleration (magnitude) that m1has?
(b) With the max amplitude, what is the net force (magnitude) acting on m1in the horizontal direction? What
force(s) provide this horizontal net force (conceptual)? Draw a free-body diagram for m1.
(c) What is the coefficient of static friction (s) between the two blocks? Given
