Answer 2

Answer:

The work done to a 15 kg mass raised up to a height of 50 m is equal to the gravitational potential energy gained by the 15 kg mass.

Solving for the gravitational potential energy gained

PE grav = mgh where m = 15 kg, g = 9.80 m/s^2 and h = 50 m

PE grav = 15 kg * 9.80 m/s*2 * 50 m

PE grav = 7,350 joules

The work done on the load of mass 15kg raised up to the height of 50m is 7,350 joules.
