Question

Calculate the momentum of a bullet of 20g when it is fired from a gun with a velocity of 100m/s

Answer 1

it should be the required answer

Answer 2

$\huge\mathfrak{\underline{\underline{Solution:-}}}$

Mass, (m) = 25g

= >$\frac{25}{1000}<strong> </strong>\times<strong> </strong>1<strong> </strong>=<strong> </strong>0.025kg$

Velocity , (v) = 100 m/s

Momentum, (p) = mv

0.025 × 100

=> 2.5 kg m/s
