A body of mass 5kg rests on a rough horizontal surface of coefficient of friction 0.2. The body is pulled through a distance of 10m by a horizontal force of 25N. Find the kinetic energy acquired by the body.
`(g=10ms^(-2))`

Text Solution

Verified by Experts

Mass=5kg, s=10m, u=0, F=25N
Resultant force : `F^(.)=F-f_(lui)=25-0.2xx5xxg=15N`
Kinetic energy=workdone by `F^(.)=15xx10=150J`
