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 The moment of inertia of the drum on which the cable is being wound is The crate starts from rest, and the motor exerts a constant couple 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.
