Same for both

Vedclass · Answer

(A) According to the work-energy theorem,the work done by the retarding force is equal to the change in kinetic energy.$W = F 	imes d = \Delta K$Since both vehicles have the same initial kinetic energy $(K)$ and come to rest,the change in kinetic energy is the same for both $(\Delta K = K)$.Given that the retarding force $(F)$ applied is also the same for both vehicles,we have:$d = \frac{K}{F}$Since both $K$ and $F$ are identical for the car and the truck,the distance $(d)$ traveled by both before coming to rest will be the same.

$A$ car and a truck are moving with the same kinetic energy. If the same retarding force is applied to both by using brakes,what will be the distance traveled by both vehicles before coming to rest?
