Lee pushes horizontally with a force of 68 N on a 25 kg mass for 30 m across a floor. Calculate the amount of work Lee did. Answer in units of J.

The amount of work Lee did is 2.0 * 10³ J

Explanation:

Hi there!

The work done on an object by a force applied in the direction of movement can be calculated with the following equation:

W = F · d

Where:

W = work done on the object.

F = applied force on the object.

d = distance traveled by the object.

In this case, we know that the force that Lee applies is 68 N and this force is applied constantly during the displacement of 30 m.

Then, applying the work equation:

W = 68 N · 30 m

W = 2.0 * 10³ J
