Question

An object of mass 70 kg is raised to a height of 10m above the ground, the potential energy is equal to (g= 10m/s^2)

Answer 1

Answer:

Given : Mass of object (m) = 70kg

Height from the ground (h) = 10 m

Gravitational acceleration (g) = 10 m/s^2

We know that :

Potential energy (P.E) = m×g×h

= 70×10×10

= 7000

Hence the potential energy will be 7000Joule
