Question
In an inelastic collision,
✓
Answer
In case of perfectly inelastic collision,
Final velocities of both the body is same
But, when the collision is not perfectly inelastic the velocities differ.
Thus, the final velocity of the bodies may or may not be same.
Also, there is a loss of kinetic energy during an inelastic collision.
thus, kinetic energy is not conserved and velocity of separation will be less than
velocity of approach.
A collision, let it be elastic or inelastic has always its momentum conserved and
is given by,
$m_1 u_1+m_2 u_2=m_1 v_1+m_2 v_2$
Thus, linear momentum of the system is conserved
