Question

The power of a crane is 25000 watt. What work will be done by it in 4 seconds?​

Answer 1

100000J

Step-by-step explanation:

Given parameters:

Power of the crane = 25000W

Time taken = 4s

Unknown:

Work done by the crane = ?

Solution:

Power is the rate at which work is being done. It is expressed as:

Power =
`(Work done )/(Time taken )`

Work done = Power x Time taken

Now insert the parameters and solve;

Work done = 25000 x 4 = 100000J
