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?

3,240 W
90 W
32.4 W
1.11 W

Answer 1

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

Hope this helps.

Answer 2

Answer : The amount of power used is, 90 W

Solution :

Formula used for power :

`P=(W)/(t)\\\\As,W=F* d\\\\So,P=(F* 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=((54N)* (10m))/(6s)=90watts=90W`

Therefore, the amount of power used is, 90 W
