Question

200N force acts on a body for 4 sec body was initially at rest change in momentum will be

Answer 1

Answer:

800 kg m/s.

Explanation:

As we know,

$F=m*\frac{v}{t}$

∴ $F=\frac{p}{t}$.

So, substituting the value of F and t,

We get,

200=p/4,

p=200*4

p=800 kg m/s.

Answer 2

Answer:

800 kgm/s

Explanation:

F=p/t

200N=p/4sec

p=800kgm/s
