Question

An object of mass 100kg is accelerated uniformly from a velocity of 4 m/s to 8 m/s in 2 seconds. Calculate the initial and final momentum of the object?​

Answer 1

Answer:

initial momentum= 4×100= 400Ns

final momentum = 8× 100 = 800 Ns

Answer 2

Answer:

We know

Momentum= mass×velocity

Here

To Find Initial momentum

Momentum (initial)=mass×initial velocity

Momentum (initial)=100×4

Momentum (initial)= 400 kgm/s

To Find Final momentum

Momentum (Final)=mass×final velocity

Momentum (Final)=100×8

Momentum (Final)=800 kgm/s

Hope it helps
