A truck and a car are moving with equal velocity. On applying the brakes both will stop after certain distance, then
Truck will cover less distance before rest
Car will cover less distance before rest
Both will cover equal distance
None
A truck and a car are moving with equal velocity. On applying the brakes both will stop after certain distance, then
Stopping distance $ = \frac{{{\rm{Kinetic\, energy}}}}{{{\rm{Retardins}}\;{\rm{\,force}}}} = \frac{{\frac{1}{2}m{u^2}}}{F}$
If retarding force $(F)$ and velocity $(v)$ are equal then stopping distance $(m)$ (mass of vehicle)
As ${m_{{\rm{car}}}} < {m_{{\rm{truck}}}}$ therefore car will cover less distance before coming to rest.
If retarding force $(F)$ and velocity $(v)$ are equal then stopping distance $(m)$ (mass of vehicle)
As ${m_{{\rm{car}}}} < {m_{{\rm{truck}}}}$ therefore car will cover less distance before coming to rest.
