Answer:
100000J
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 = [tex]\frac{Work done }{Time taken }[/tex]
Work done = Power x Time taken
Now insert the parameters and solve;
Work done = 25000 x 4 = 100000J
