A $50$ gm ball collides with another ball of mass $150$ gm. moving in its direction of motion, After the collision, the two balls move at an angle $30$ with their initial direction. A ratio of their velocities after the collision is:

Open in App

Solution

mass of each ball $= 50 g = 50 / 1000 = 0.05 k g$
initial velocity $= 16 m / s$

Initial momentum $= P 1 = m * u$
$= 16 x 0.05$
$= 0.8 k g m / s$

After collision, the direction of velocity of each ball is reversed on rebounding.

Final momentum $= P 2$
$= m (- v)$
$= 0.05 x (- 16)$
$= - 0.8 k g m / s$

Impulse imparted= Change in momentum of each ball

$= - 0.8 - (0.8)$

$= - 0.16 k g m / s$

Impulse imparted due to one ball after collision on another would be $- 0.16 k g m / s$
