A truck and a car are moving with equal velocity. On applying brakes, both will stop after a certain distance, then?
Correct answer: B. Car vill cover less distance before stopping
- A. Truck will cover less distance before stopping
- B. Car vill cover less distance before stopping
- C. Both will cover equal distance
- D. None of the mentioned
Explanation
Being lighter than a truck, the car has less kinetic energy. On applying brakes with the same force, the car will cover less distance before coming to rest.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
