The 56.28 kg crate is hoisted up the 0 = 27° incline by the pulley system and motor M. If the crate starts from rest and, by constant acceleration, attains a speed of 8.17 m/s after traveling 7.84 m along the plane, determine the supplied power to the motor if the crate has moved 8 m and the coefficient of kinetic friction between the plane and the crate is Hk = 0.3. Neglect friction along the plane. The motor has an efficiency of 0.691.

Question
The 56.28 kg crate is hoisted up the 0 = 27° incline by
the pulley system and motor M. If the crate starts from
rest and, by constant acceleration, attains a speed of
8.17 m/s after traveling 7.84 m along the plane,
determine the supplied power to the motor if the crate
has moved 8 m and the coefficient of kinetic friction
between the plane and the crate is Hk = 0.3. Neglect
friction along the plane. The motor has an efficiency
of 0.691.
