A dog is pulling a sled by applying a force of 75 newtons on it. The angle of force from the ground is 45°. If the sled moves 15 meters, how much work is done by the dog on the sled?

Respuesta :

Work done = force x distance (where the force is in the direction of the distance travelled)
We must resolve the force so that it is horizontal to the ground
force = 75cos45
Then simply plug into the formula, so:
work done = 75cos45 x 15 = 795.49... Nm = 795 Nm (3 sig. fig.)
