The block is displaced 4.50 m, and the coefficient of kinetic friction is 0.268. a. Find the work done by the 70.9 N force. b. Find ; A block of mass m=5.0 kg. is being pulled along a rough, horizontal surface by a rope attached near the top of the block at an angle of 30 degrees to the postive, horizontal axis. The 50 kg mass returns to the ground with a speed of 20 m/s, which is exactly the same as the speed of the 25 kg mass. If there was no air resistance or drag, the 25 kg mass and the 50 kg would W =F d W = F d. However, most forces are not constant and will depend upon where exactly the force is acting. So, let's suppose that the force at any x x is given by F (x) F ( x). Then the work done by the force in moving an object from x = a x = a to x = b x = b is given by, W =∫ b a F (x) dx W = ∫ a b F ( x) d x.

Calculate the work done on the box if the box is displaced 5 meters. (1.b) Since the box is displaced 5 meters and the force is 2 N, we multiply the two quantities together. .
