A winch has a maximum power output of 500 W. It is dragging a 200 kg crate up a slope inclined at 30° to the horizontal. The coefficient of friction between the crate and the slope is 0.6. (a) Find the work done in dragging the crate a distance a m up the slope. (b) Hence find the maximum speed at which the winch can drag the crate.
