A 64.0 kg man, standing on a frictionless walkalator inclined at 0=33.0° below the horizontal, holds a 10.1 kg grocery cart. The walkalator moves a at constant speed while it carries the cart through a height of 14.7 m from the higher floor to the lower floor of a mall. If the man applied a force that is parallel to the walkalator, how much power is delivered by the man on the cart if it reaches the lower floor after 20.9 s?
