1.	A car of mass 200 kg is moving with an initial velocity of 20 m/s and after t seconds the final velocity of the car becomes 40 m/s. Calculate the change in momentum of the car
Answer» ANSWER: GIVEN, Mass = 200kg Initial velocity (u) = 20m/s FINAL velocity (v) = 40m/s To find:- CHANGE in momentum *For* *initial* *momentum,* By applying, P =mu = 200×20 = 4000kgm/s. *Foe* *final* *momentum,* By applying, P =mv = 200×40 = 8000kgm/s. Change in momentum, P2 - P1 = 8000-4000 = 4000kgm/s.

Answer»

ANSWER:

GIVEN,

Mass = 200kg

Initial velocity (u) = 20m/s

FINAL velocity (v) = 40m/s

To find:-

CHANGE in momentum

For initial momentum,

By applying, P =mu

= 200×20

= 4000kgm/s.

Foe final momentum,

By applying, P =mv

= 200×40

= 8000kgm/s.

Change in momentum, P2 - P1

= 8000-4000

= 4000kgm/s.
