two smooth spheres of masses 2kg and 4kg collide obliquely . the 2 kg mass is brought to rest. the coefficient of restitution is 1/2
prove before the impact the spheres were moving in perpendicular directions to each other and find their velocities before and after the collision.

using conservation of momentum. 4x+2y=4p+2(0) where x and y are velocities before impact. p is velocity after impact of 4kg

the velocity in the j direction does not change as its along the i axis

newtons experimental law p-0/x-y =-1/2 dont know what to do next
