Answer 1

Answer:

When a force 1N acts on 1kg mass at rest for 1s it's final momentum is p. when 1N force acts on 1kg mass at rest through a distance 1m it's final momentum is p'.

Answer 2

Answer:

1:

Explanation:

Correct option is B)

F=1N,t=1S

△P=F×t=1N×1S=1kgm/s

Pf−Pi=1kgm/s

Pf−0=1kgm/s

Pf=1kgm/s

F=1N,M=1kgm,S=1m

a=MF,1Kg1N=1m/s2

Vf2−Vi2=2as

Vf2−0=2(1m/s2)(1m)

Vf=2ms

multiply both sides 

mvf=2m/s×1kg

P′=2kgm/s

p′p=21=21=1:2
