Two boxes, m1 = 1.0 kg with a coefficient of friction of 0.10, and m2 = 2.0 kg with a coefficient of 0.20, are placed on a plane at 30o above the horizontal.

a. What acceleration does each block experience?

b, If a taut string connects the blocks, with m2 initially further down the incline then m1, what is the acceleration of each block?

c. In the initial acceleration is reversed with m1 starting lower with a taut string, what is the acceleration of each block?
