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,

[tex]P=\frac{W}{t}[/tex]

Where,

P = Power = 4400 W or 4400 J/s

W = Work done = ? J

t = Time taken = 200s

Putting values in above equation, we get:

[tex]4400J/s=\frac{W}{200s}\\\\W=880000J[/tex]

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.

[tex]Power(P)=\frac{W}{T}[/tex]

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 =?

[tex]P=\frac{W}{T}[/tex]

[tex]W=P\times T=4400 W\times 200s =880,000 J[/tex]

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

880,000 J

Explanation:

P = W/t

4400 W = W / 200 s

W = 880,000 J

Explanation:

i took the test

A 4400-watt motor, running flat out at maximum capacity,
is delivering, let's say, 4400 watts of power.
That means 4400 Joules of energy every second.

In 200 seconds, if it doesn't fail under the extreme load,
it'll deliver

(4400 joules/second) x (200 seconds)

=  880,000 joules

Hope this helps, have a great day ahead!

So if p=w/t
then 4400=(w)(200)
so you would multiply 4440•200 and get 880,000

We know,  P = w / t
4400 = w / 200
w = 4400 * 200
w = 880000 J

Hope this helps!
