A pump is used to raise water from a rainwater collecting vessel to a storage tank on a raised platform.
Every minute, the pump raises 15 kg of water through a vertical height of 8.0 m.
Calculate the increase in the gravitational potential energy of the 15 kg of water when it is raised 8.0 m.
Calculate the useful power output of the pump as it raises the water.
