Problem

In a two-block system, m1=3 kgm_1 = 3\,\text{kg} lies on a horizontal surface where μs=0.40\mu_s = 0.40 and μk=0.30\mu_k = 0.30. It is connected over a smooth pulley to a hanging mass m2=1.5 kgm_2 = 1.5\,\text{kg}. When the system is released from rest, which of the following describes its subsequent motion? (a) System remains at rest (zero acceleration). (b) Blocks move with acceleration 1.3 m s−21.3\,\text{m s}^{-2}. (c) Blocks move with acceleration 0.65 m s−20.65\,\text{m s}^{-2}. (d) Blocks move with acceleration 2.0 m s−22.0\,\text{m s}^{-2}.
