A 50 newton force is required to push a 10 kg box 30 meters across the floor. The box is then lifted up 6 meters and placed on a shelf. How much total work was done?

2088 J

Explanation:

Work = net force * distance

When the box is being pushed across the floor, the force is 50 N, and the distance is 30 m.

W = (50 N) (30 m)

W = 1500 J

When the box is being lifted, the force is the weight of the box (10 kg * 9.8 m/s²), and the distance is 6 m.

W = (98 N) (6 m)

W = 588 J

So the total work done is:

W = 1500 J + 588 J

W = 2088 J
