Question

A bullet of mass 100 kilogram is fired from the rifile of mass 200 kilogram with the speed of 50 m/s calculate the recoil velocity of gun

Answer 1

Answer:-

• Mass of bullet=m1=100g=0.1kg

Fact:-

No bullet weighs 100kg

• Mass of Rifle=200kg=m2
• initial velocity=u=50m/s
• recoil velocity=v=?

We know

$\boxed{\sf ∆P=P}$

$\\ \sf\longmapsto m_1u=m_2v$

$\\ \sf\longmapsto (0.1)(50)=200v$

$\\ \sf\longmapsto 5=200V$

$\\ \sf\longmapsto V=\dfrac{5}{200}$

$\\ \sf\longmapsto v=0.02m/s$

Recoil velocity is 0.02m/s.
