Question

A force of 24 N causes a displacement of 5 m in 12 s. Calculate the power.

Answer 1

Answer:

10 Watt

Explanation:

F = 24 N

s = 5m

t = 12s

P = ?

P = $\frac{W}{t}$ = $\frac{F s}{t}$   [since, W = F x s]

So, P = 24 x 5 / 12

P = 10 W

Answer 2

First find the workdone

workdone = force × displacement

workdone = 24 × 5

work done = 120 J

Power = workdone / time

Power = 120 / 12

Power = 10 W
