19.32 The 45-kg crate is pulled up the inclined surface by the winch. The coefficient of kinetic friction between the crate and the surface is μ = 0.4. The moment of inertia of the drum on which the cable is being wound is IA = 4 kg-m². The crate starts from rest, and the motor exerts a constant couple M = 50 N-m on the drum. Use the principle of work and energy to determine the magnitude of the velocity of the crate when it has moved 1 m. 20° 0.15 m M
