A4400 w motor is used to do work. if the motor is used for 200 s, how much work could it do? (power: p = w/t)

22 j
4200 j
4600 j
880,000

The amount of work done by the motor is 880000 J.

Explanation:

Power is defined as the amount of work done in unit time.

Mathematically,

Where,

P = Power = 4400 W or 4400 J/s

W = Work done = ? J

t = Time taken = 200s

Putting values in above equation, we get:

Hence, the amount of work done by the motor is 880000 J.

The work done by the motor is 880,000 Joules.

Explanation:

Power is work done per unit time. or it can also be defined as ratio of work done to time taken to complete the work.

Where:

W = Work done in time T.

T = Time taken to complete the work

Here, we have, Power of the motor = P = 4400 Watt 4400 J/s

Time interval for which motor performed work = T = 200 seconds

Work done by the motor = W =?

The work done by the motor is 880,000 Joules.
