Randall D. Knight — Newton's Third Law: Problem Problem_39
FIGURE P7.39 shows a block of mass \( m \) resting on a \( 20^\circ \) slope. The block has coefficients of friction \( \mu_s = 0.80 \) and \( \mu_k = 0.50 \) with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass \( 2.0\text{ kg} \). (a) What is the minimum mass \( m \) that will stick and not slip? (b) If this minimum mass is nudged ever so slightly, it will start being pulled up the incline. What acceleration will it have?
