1.

An object of mass 100kg is accelerated uniformly from a velocity of 4m/s to 8m/s in 2s.calculate the initial and final momentum of the objecta)800kgm/s, 400kgm/sb)400kgm/s, 800kgm/sc)200kgm/s, 400kgm/sd)400kgm/s, 200kgm/s​​

Answer»

Answer:

option B is the CORRECT answer......

It is given that,

mass=100kg

initial velocity=4m/s

Final VELOCITY,=8m/s

time=2s

Now,

Initial momentum,p=mu=400kgm/s

final momentum,p=mv=800kgm/s

Explanation:

Hope it HELPS you FRND.....
