Solution

The correct option is B lorry comes to rest in shorter distance.
Momentum, $p = m v$ or $v = p / m$
As momentum is constant, so less mass will give more velocity.
Thus, the car has more velocity than that of the lorry.
Acceleration, $a = F / m$
As force is constant, so less mass body has more acceleration.
Thus, the car has more acceleration than that of the lorry.
Hence, the car will travel more distance comes to rest than that of lorry.
