Question

A wheel of mass 38 kg is lifted to a height of 0.8 m. How much gravitational potential energy is added to the wheel? Acceleration due to gravity is g = 9.8 m/s2.

Answer 1

Gravitational potential energy, E = 297.92 J

Step-by-step explanation:

Mass of the wheel, m = 38 kg

Height, h = 0.8 m

The gravitational potential energy is said to be possessed by an object due to its height above ground surface. Mathematically, it is given by :

`E=mgh`

g is the acceleration due to gravity

`E=38* 9.8* 0.8`

E = 297.92 Joules

So, the gravitational potential energy added to the wheel is 297.92 Joules. Hence, this is the required solution.
