An elephant pushes with 2000 N on a load of trees. If it takes the elephant 45 seconds to move trees 15 meters, how much power did the elephant generate?

Power generate by elephant = 666.67 W

Explanation:

Given:

Force = 2,000 N

Change in time = 45 Seconds

Distance = 15 meter

Find:

Power generate by elephant ?

Computation:

⇒ Work Done = Force × Distance

⇒ Work Done = 2,000 × 15

⇒ Work Done = 30,000

⇒ Power = Work Done / Time taken

⇒ Power generate by elephant = 30,000 / 45 seconds

⇒ Power generate by elephant = 666.67 W

another example of kinetic energy would be,

kinetic energy   >     moving energy
