Homework Answers
During collision momentum is conserved
Initial momentum = Final momentum
---------(1)
==========================
Since the collision is perfectly elastic, kinetic energy is also conserved
Initial kinetic energy = Final kinetic energy
Put (1) in the above equation
Multiply all terms with 8
