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

hey
____

•inertia - the tendency of an object to remain at rest or in uniform motion on a straight line until and unless compelled by an external force

• as we know that inertia is directly proportional to mass and velocity

• more the mass more the inertia it has

• less the mass , less the inertia it has

• so the loaded truck will require a larger force to stop , so it will not stop first

•hence, the empty truck will stop first as it has less mass and less inertia

hope helped
__________

Answer 2

Answer:

a loaded truck has more inertia. Because the inertia of a body is directly proportional to its mass, i.e., greater the mass, greater is the inertia.

hence, a loaded truck will stop first
