Question

Calculate the work done in lifting 100 kg of water through a vertical height of 5 m.

Answer 1

Explanation:

will be 5000 Joules

m= 100 kg

g= 10 Newton

h= 5 metres

work equals to MGH

so w = 100 X 10 X 5

w = 5000 Joules

Answer 2

Work done in lifting 100 kg of water through a vertical height of 5 m is 5000 joules.

Given,

Weight of water = 100kg.

Height= 5m.

To Find,

Work done for lifting the water.

Solution,

We can subsequently solve the problem.

Now,

W = m×g×h

g = 10m/s

W = 100× 5× 10

= 5000joule.

Hence, work done in lifting 100 kg of water through a vertical height of 5 m is 5000 joules.
