Physics - Center of Mass Question with Solution | TestHub

A particle of mass$m$is moving with speed$2\text{v}$and collides with a mass$2m$moving with speed$\text{v}$in the same direction. After the collision, the first mass is stopped completely while the second one splits into two particles each of mass$m,$which move at an angle${45}^{\mathrm{o}}$with respect to the original direction. The speed of each of the moving particle will be
