Question

Suppose a force of 100 N is used to push an object a distance of 5 meters in 15 seconds: Find the done and the power for this situation.

Answer 1

Explanation:

Remark

You need the work done (I think), and the power developed from the givens. This question is just a straight forward application of the formulas for work and power.

Givens

F = 100 N

d = 5 meters

t = 15 seconds

Formulas

W = F * d

Power = F * d / t

Solution

Work

W = 100 N * 5 meters

W = 500 Newton Meters or 500 J

Work = 500 Joules

Power

P = F * d / t

Power = 100 * 5 / 15

Power = 33.3 Watts.
