Question

How much power is used if a force of 54 newtons is used to pull a wagon a distance of 10 meters in 6 seconds?

Answer 1

Answer : The amount of power used is, 90 W

Solution :

Formula used for power :

$P=\frac{W}{t}\\\\As,W=F\times d\\\\So,P=\frac{F\times d}{t}$

where,

P = power

W = work done

F = applied force = 54 N

d = displacement = 10 m

t = time taken = 6 s

Now put all the given values in the above formula, we get the amount of power used.

$P=\frac{(54N)\times (10m)}{6s}=90watts=90W$

Therefore, the amount of power used is, 90 W

Answer 2

First, calculate the work done: 54 x 10 = 540J.
Now calculate power: 540 / 6 = 90.
The answer is 90W.

Hope this helps.
