PhysicsEasysingle choice

A particle strikes elastically with another particle with velocity $V$ . After collision, it moves with half the velocity in the same direction. Find the velocity of the second particle if it is initially at rest.

Options:

Answer:

Solution:

We know that

$(\vec{v_{2}} - \vec{v_{1}}) = e (\vec{u_{1}} - \vec{u_{2}})$

or $(\vec{v_{2}} - \frac{v}{2}) = 1 (v - 0)$ (for an elastic collision $e = 1$ )

or $v_{2} = \frac{3 V}{2}$
