Question

Please solve with full explanation.​

Answer 1

Answer:-

• Mass of bullet=20g=0.02kg
• Uniform Velocity=u=150m/s
• Mass of pistol=2kg
• Recoil Velocity=v=?

We know that

$\boxed{\sf ∆P=P}$

$\\ \sf\longmapsto mu=mv$

$\\ \sf\longmapsto 0.02\times 150=2v$

$\\ \sf\longmapsto 3=2v$

$\\ \sf\longmapsto v=\dfrac{3}{2}$

$\\ \sf\longmapsto v=1.5m/s$
