Question
A mass ‘m’ moves with a velocity ‘v’ and collides in elastically with another identical mass at rest. After collision the 1st mass moves with velocity $\frac{v}{\sqrt{3}}$ in a direction perpendicular to the initial direction of motion. Find the speed of the 2nd mass after collision
Options
A.$\frac{2v}{\sqrt{3}}$
B.$\frac{v}{\sqrt{3}}$
C.$v\sqrt{\frac{2}{3}}$
D.the situation of the problem is not possible without external impulse
Solution
Sol. Final energy becomes more than initial energy.
