A solid block of mass m = 1 kg is resting on a horizontal platform as shown in figure. The z direction is vertically up. Coefficient of friction between the block and the platform is mu = 0.2. The platform is moved with a time dependent velocity givenby vecV = (2thati + thatj+ 3thatk)m//s . Calculate the magnitude of the force exerted by the block on the platform.Take g = 10 m//s^(2)
