Question

Calculate the potential energy of a 6kg bowling ball suspended 3m above the surface of the earth

Answer 1

Answer: 176.4 Joules

Explanation: Potential energy of a body is defined as the energy possessed by virtue of position.

Potential energy
`=m* g* h`

m = mass of the body = 6 kg

g = acceleration due to gravity =
`9.8 ms^(-2)`

h = height of body = 3 m

Potential energy
`=6 kg* 9.8ms^(-2)* 3m=176.4kgm^2s^(-2)`

= 176.4Joules {
`1kgm^2s^(-2)=1Joule`}
