Figure shows the 60 kg concrete block is pull by electric motor. The force or tension in cable is about F = (400t 1/2 ) N, that the t is in seconds. By using Principle of Newton Law, determine the concrete block’s velocity for t = 6 s. Assuming it is originally at rest and the coefficient of static and kinetic friction between the concrete bock and the floor surface are about µ s = 0.5 and µ k = 0.4, respectively
