Two boxes, m1 = 1.0kg with a coefficient of kinetic friction of 0.10, and m2 = 2.0kg with a coefficient of 0.20, are placed on a plane inclined at 0 = 30o.
(a) What acceleration does each box experience?
(b) If a taut string is connected to the boxes (Fig. 4-64), with m2 initially farther down the slope, what is the acceleration of each box?
(c) If the initial configuration is reversed with m1 starting lower with a taut string, what is the acceleration of each box?
