Answer:
A garage hoist lifts a truck up 2 meters above the ground in 15 seconds. Find the power delivered to the truck.
Explanation : [Given: 1000 kg as the mass of the truck] First we need to calculate the work done, which requires the force necessary to lift the truck against gravity: F = mg = 1000 x 9.81 = 9810 N. W = Fd = 9810N x 2m = 19620 Nm = 19620 J.
