Question

What is the potentual energy of 7 kg object, 12 m off the ground?​

Answer 1

Required Answer:-

Mass=m=7kg

Height=h=12m

Gravitational force=g=10m/s^2

• As we know that

`{\boxed{\sf Potential\:energy{}_((P.E))=mgh}}`

• Substitute the values

`{:}\longmapsto`
`\sf P.E=7×12×10`

`{:}\longmapsto`
`\sf P.E=84×10`

`{:}\longmapsto`
`\sf Potential\:energy=840Joule`

Answer 2

823.2 J

Step-by-step explanation:

PE = mgh

= (7 kg) (9.8 m/s^2) (12 m)

= 823.2 J
