Calculate power crane has 10000 J for 100 sec

100 Watts

Explanation: Power is the rate at which work is done. Power is measured in Joules per second or watts. It is calculated by dividing work done in joule by time taken in seconds.

Power = Work done : time

In this case;

Work done = 10,000 Joules

Time = 100 sec

Therefore;

Power = 10,000 Joules : 100 sec

= 100 J/s

Therefore, the power of the crane is 100 watts
