Answer 2

$<b> Heya! </b>$

____________________________________________________________

Ques. → $<u> A rifle of mass 3 kg fires a bullet of mass 0.03 kg. The bullet leaves the barrel of the rifle at a velocity of 100 m/s . If the bullet takes 0.003 seconds to move through its barrel , calculate the force experienced by the rifle due to this recoil ❗ </u>$

Solution → We know that ,

$<b> Force = Mass × Acceleration </b>$

Also ,

$<b> Acceleration = Velocity / Time </b>$

Therefore we have ,

$= > f = m \: \times \frac{v}{t} \\ \\ = > f \: = 0.03 \times \frac{100}{0.003}$

•°• $<b> <u> The force is -1000 N </b> </u>$


[ The -ve sign is an indication that force acts in the opposite direction !!]
