From a rifle of mass 4 \(kg\), a bullet of mass 50 \(g\) is fired with an initial velocity of 35 . Calculate the initial recoil velocity of the rifle.
(Note: Enter the values up to three decimal)
Let us consider,
\(m_1\) be the mass of the bullet
\(m_2\) be the mass of the riffle
\(v_1\) be final velocity of the bullet
\(v_2\) be final velocity of the riffle
\(u\) be the initial velocities of the bullet and riffle before the collision
From the law of conservation of momentum, We know that,
Recoil velocity of the riffle \(=\) .
