A truck and a car are moving with the same K.E. on a straight road. Their engines are simultaneously switched off. Which one will stop at a lesser distance ?

Answer»

Solution :By Work -ENERGY Theorem Loss in K.E. =W.D. against the force `XX` distance of friction
or K.E. `=mu mg S`
For cosntant K.E. `=S prop 1/m`
`:.` TRUCK will stop in a LESSER distance.
