●●●●●●●●●●●●●●●●●●●●

GIVEN DATA :-
▪▪▪▪▪▪▪▪▪▪

FORCE =200N

MASS=2KG

TIME = 10s

●●●●●●●●●●●●●●●●●●●

REQUIRED :-
▪▪▪▪▪▪▪▪▪▪

MOMENTUM =?

●●●●●●●●●●●●●●●●●●●

FORMULA :-
▪▪▪▪▪▪▪▪▪

P=m ×v

v= a × t

a =F÷m

a=200÷2

a=100m/s^2

v=a × t

v= 100 × 10

v=1000m/s

NOW

P=m × v

P=2 × 1000

so momentum =2000 kg m/s

●●●●●●●●●●●●●●●●●●●●●

Or


ACCORDING TO NEWTON 2ND LAW OR WE CAN SAY LAW OF CONSERVATION OF MOMENTUM

P=F × t

P=200 × 10

P=2000 Ns
