Question

two particle of mass m1 traviling m2 along the same straight line with velocity u1 and u2 collicle with each other if the collision is head on elastic collision find their velocity after collision?​

Answer 1

A::C::D

Solution :

Since both masses have equal kinetic energy, so

<br>

<br> By law of conservation of momentum <br>

<br>

<br>

<br> Further by law of conservation of energy, we have <br>

<br>

<br>

<br> From Eqs ii and iii we get <br>
