A motor winds the rope in B with a constant acceleration ab. Because of the pulley system, the mass m in A slides in this way to the left over a horizontal axis. Between m and the left end point of the horizontal axis, there is a spring (constant k, unstretched length ). The coefficient of kinetic friction between m and the axis is μK. When SA equals 1.5 m, Vв equals 6 m/s. For this situation, determine at that instant the velocity of A and the acceleration of A. Data: aв = 2 m/s², m = 2 kg, k = 150 N/m, lo = 2 m, μK = 0.3 2 m SA A B A motor winds the rope in B with a constant acceleration ab.
