8. A motor pump expends 20,000 J of energy and in doing so, it raises 200 kg of
water to the top of a building. If g = 10 m/s?, calculate the height of the building.

Answer:
Energy of the Motor Pump = 20,000 J
Mass of the Water = 200 kg
Acceleration Due To Gravity = 10 m/s2
Height = x
AS THE ENERGY IS STORED AT SOME HEIGHT,
Energy = mgh
20,000 = 200 * 10 * x
20,00 = 2000x
x = 20,000/2000
x = 10 metres
Therefore the Height of the Building is 10 Metres

Answer:
Work done/ energy created by the motor pump=20000J
mass of the water raised =200kg
g=10m/s
Height=?
Let the height be 'h'
Now.,
W. D=mgh
20000 =200*10*h
20000/2000=h
h=10m
Therefore height of the building is 10m.
