Question

An empty truck and a loaded truck are moving with the same velocity.On applying brakes, which truck will stop first and why?​

Answer 1

Answer:

It takes more distance to stop the heavier truck.

Explanation:

Greater the mass greater would be the momentum. Also both the trucks have the same velocity therefore loaded truck possesses large momentum and hence it takes more distance to stop the heavier truck.

Since velocity is the same, momentum of the truck is directly proportional to its mass. The loaded truck has greater momentum than the empty truck. We will need greater force to stop an object with higher momentum or a greater mass. So the loaded truck requires more force to stop it than the empty truck.

Greater the mass greater would be the momentum. Also both the trucks have the same velocity therefore loaded truck possesses large momentum and hence it takes more distance to stop the heavier truck.

Since velocity is the same, momentum of the truck is directly proportional to its mass. The loaded truck has greater momentum than the empty truck.
