Question

Aforce of 100 dyne acts on a mass of 100 gm at rest for 5 sec calculate the impulse and fonal momentum?​

Answer 1

Answer:

f= 100

m=100 gm            [ 100 gm=0.1 kg] AND 0.1 CAN BE WRITTEN AS 1/10

t=5 sec

I=?

P?

Explanation:

I= FT and p=mv

I= 100[5]

= 500 N-SEC

BY THE INERTIA OF MOTION

P  =  I

MV=FT

1/10[V]=500

V=500[10]

V=5000

THERE FORE P= MV

P= 1/10[5000]

P= 500
