Challenges in mechanics by Ronak Agarwal(Part 3)

A thin rod AB of mass m1m_{1} and of length ll is placed on a smooth horizontal ground. A point sized particle of mass m2m_{2} having a velocity vv making an angle θ\theta with the line perpendicular to ABAB collides with the rod at point AA.

Assuming the collision to be elastic find 100tan(θ)\lfloor 100 \tan(\theta) \rfloor such that the point sized particle again collides with the rod at point BB.

Details and assumptions:

  • m1m2=12π+2\dfrac{m_{1}}{m_{2}}=\dfrac{12}{\pi}+2

Also try Solve for trajectory Again
