Initially, block A has a speed of 3 m/s as shown. Determine the speed of block B at t = 6 seconds. The coefficient of static friction between block A and the surface is Ms = 0.50 and the coefficient of kinetic friction Mk = 0.15. The length of the cable is 10 meters. also show how you relate the two different accelerations. Initially, block A has a speed of 3 m/s as shown. Determine the speed of block B at t = 6 seconds.
