A lorry and a car are brought to rest by the same breaking force. What is the difference in the distance covered by them before they come to stop if their kinetic energies are equal?

Answer:
Simplest answer to your question lies in concept of inertia.
Larger the mass, greater the inertia of motion.
Also greater thE momentum.
Lorry will have greater momentum than car. And though you apply the same breaking force, as you have applied to car to come to stop the acceleration produced in lorry will be smaller than that produced in car.
Hence lorry will cover large distance than car
