When a body is in the state of complete rest, what kind of energy does it possess?
a) Potential energy
b) Kinetic energy
c) Total energy
d) Heat energy

Answer

B

Explanation

`t=1 min 57.56sec =117.56sec
`p=460W, s=200m`
`p=W/t`
work`W=pt=460xx117.56J`
Again `W=FS`
`rarr F=W/S`
`=(460xx117.56)/200`
`270.3=270N`
