Problem
A traveller pulls a suitcase along a level platform by exerting a constant force of magnitude 40N on the handle. The suitcase moves 30m in the forward direction, and the work done by the force on the suitcase is found to be 600J.
(i) Calculate the angle between the direction of the force and the displacement.
(ii) If the force is increased to 60N while the angle found in part (i) and the displacement remain unchanged, determine the new amount of work done on the suitcase.
