Two boxes, m1 = 1.0 kg with a coefficient of kinetic

Chapter 19, Problem 87GP

(choose chapter or problem)

Two boxes, \(m_{1}=1.0 \mathrm{~kg}\) with a coefficient of kinetic friction of 0.10, and

\(m_{2}=2.0 \mathrm{~kg}\) with a coefficient of 0.20, are placed on a plane inclined at \(\theta=30^{\circ}\)

(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?
