The 61 kg crate is moved up the surface with a 30° inclination using the pulley system and motor M shown in the figure. If the box starts from rest and, with constant acceleration, reaches a velocity of 4 m/s after traveling a distance of 6.0 meters along the surface, determine the power that must be supplied to the motor at that instant. . Neglect friction along the inclined surface. Express the answer in kW. The efficiency of the motor is n = 0.79.
