Answer 2

Question ::-

A stone of mass 5 kg is lying at the edge of a cliff of 80 m vertical height from the ground level. Calculate the potential energy of the stone. [Take g = 9,8 m/s]

Given ::-

• Mass of stone = 5 kg.

• Height from the ground level = 80 m

• g = 9.8 m/s

To find ::-

• Calculate the potential energy ?

Solution ::-

• Potential energy = u
• Mass = m
• Gravity = g
• Height= h

_________

U = mgh

U = m × g × h

U = 5 × 9.8 × 80

U = 400 × 9.8

U = 3920 Joule.

________

So, potential energy is 3920 joule
