  • The work done by the pump is 13475 J.
  • The power of the pump is 385 W.

Step-by-step 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.
