- The work done by the pump is 13475 J.
- The power of the pump is 385 W.
Explanation:
When a force causes a body to move work is being done on the object by the force. Work is the measure of energy transfer when a force moves an object through a distance. The work done is the product of mass, gravity, and height.
Work done = m * g * h
= 55 * 9.8 * 25
Work done = 13475 J.
Power is defined as the rate of doing work with time.
Power = work done / time
= 13475 / 35
Power = 385 W.
