A 5,400 W motor is used to do work. If the motor is used for 640 s, about how much work could it do?

Since P=E/t,
where P=power (W),
E=energy (J) and
t=time (s).

Just rearrange this formula to obtain E=Pt=5400640=3456000 J.

Energy and work are very related since energy is defined like the ability of doing work. Actually work is also measured in J so the answer is the one above.
Work = 3456000 J

Work is defined as the conversion of energy. The given motor can give 3456000 J of work.

Power:

It is defined as the ability of a machine to do work or as the time rate of energy conversion.

P=E/t,

E = P x t

Where,

P = power = 5,400 W

W = energy (J) = ?

t = time = 640 s

Put the values in the formula,

W= 5400 x 640

W = 3456000 J.

Therefore, the given motor can give 3456000 J of work.
