Question

in which case will there be larger change in momentum of the object a 150 in force act for 0.1 second on a 2kg object initially at rest or a 150 in force acts for 0.2 second on a 2 kg object initially at rest

Answer 1

As we know that.

Momentum = mass x velocity

And

Velocity is equal to displacement upon time.. So it means momentum is inversely proportional to the time.

So more the time less the momentum.

Answer 2

Answer:

a 150 in force acts for 0.2 second on a 2 kg object initially at rest

Explanation:

In case (b) the change in momentum will be larger. It is the F Δt product that

gives the change in momentum.
