A cable pulls a crate of mass 19.0 kg across the floor in 6.8s. If the total distance traveled is 5.40 m, find the power used by the cable.

(19)*(9.8)*(5.4)/(6.8) )
147.9 W

Raul pushes a stalled car with a force of 204 N. If the required force decreases at a constant rate from 204 N to 44.0 N for a distance of 16.3 m in 16.0 s, calculate the average power required to move the car.

(1/2)*(204 + 44)*(16.3)/(16.0) )
126 W
