- A shopper pushes a grocery cart 36.6 m on level ground, against a 13.1 N frictional force. The cart has a mass of 15.2 kg. He pushes in a direction 17.8º below the horizontal. If the initial velocity was 1.8 m/s, and final speed was 15.4 m/2. What is the work done by the pushing force in unit of Joule?A heavy rope, 50 ft long, weighs 0.3 lb/ft and hangs over the edge of a building 140 ft high. (a) How much work W is done in pulling the rope to the top of the building? W = ft-lb (b) How much work W is done in pulling half the rope to the top of the building? W = ft-lbAn object is moved on a horizontal surface by a force of 15 N up to a distance of 10 m. The force of kinetic friction is 7.5 N. What is the work done by the resultant force?
