Question

If a man lifts a 10 kg box at a constant speed to the car trunk a distance of 6 meters (how much is the work done by the man on the box?

Answer 1

Answer:

Workdone = 588 Nm

Explanation:

Given the following data;

Mass = 10 kg

Distance = 6 meters

To find the work done by the man on the box;

First of all, we would determine the force acting on the box;

Force = mass * acceleration due to gravity

Force = 10 * 9.8

Force = 98 N

Next, we find the workdone;

Workdone = force * distance

Workdone = 98 * 6

Workdone = 588 Nm
