Question

Arjun change the speed of the car from 2 metre per second to 5 metre per second if the mass of the car is 1 ton what is the change in momentum​

Answer 1

Answer:

Δ p = 3000 kg m / sec

Explanation:

Given :

Initial speed of car ( u )  = 2 m / sec .

Final speed of car ( v )  = 5 m / sec .

Mass of car = 1 ton

In term of kg Mass = 1000 kg .

We have find change in momentum :

Δ p = m Δ v

Δ p = m ( v - u )

Putting values here we get

Δ p = 1000 ( 5 - 2 ) kg m / sec

Δ p = 1000 × 3  kg m / sec

Δ p = 3000 kg m / sec

Thus , change in momentum is 3000 kg m / sec

Answer 2

SOLUTION:-

Change in Momentum:

Mass× (change in velocity)

Given:

Initial value of the car, (u)= 2m/s

Final value of the car, (v)= 5m/s.

Mass of the car= 1 ton [1000kg].

Therefore,

We know that change in momentum is given above:

So,

∆p= m(v-u)

where, m= 1000kg

=) ∆p= 1000(5-2)kg.m/s

=) ∆p= 1000(3)kg.m/s

=) ∆p= 1000× 3kg.m/s

=) ∆p= 3000kg.m/s

Hence,

change in momentum is 3000kg.m/second.

Hope it helps ☺️
