Question

a mechanic uses a hydraulic lift to raise a 1,200 kg car 0.50 m off the ground . how much work does the lift do on the car

Answer 1

Answer:

The work done is 5880 J

Explanation:

Recall the formula for work as force times distance, therefore in this case the force is that oppose to the gravitational force on the car(of magnitude m * g), and the distance is 0.5 meters.

Then:

Work = 1200 * 9.8 * 0.5 J = 5880 J
