Question

if body of mass 2kg moving with 15 m/s collide with stationary body of same mass then after elasitic collisoon the 2nd body will move with velocity ( kindly explain with mathemtical proof)​

Answer 1

$\huge\pink{Answer}$

Explanation:

By conservation of linear

$2v0 = 2( \frac{v0}{4}) + mv = = > 2v0 = \frac{v0}{2} + mv = = > \frac{3v0}{2} = mv....1$

since collision is elastic

$v \: separation=v \: apprach⇒v−4v0=v0⇒45v0=v....(2)</p><p>$

$\frac{mv0}{4} = m( \frac{5v0}{4} ) = > m = \frac{6}{5} = 1.2kg$

Hope it's helpful to you!
