Answer:

2250 J

Explanation:

Work is the result when a force acts on an object and moves it by some distance and it is calculated in Joules. So here distance equals 25m and force equal 90N.

Formula:

The force and the distance covered was in the same direction, so the angle between them is 0°. The work can be found using the formula:

W = Fd cosθ

W = Fd cos0

W = Fd(1)

W = (90 N)(25 m)

W = 2250 Nm

W = 2250 J
