Question

A body of mass m, = 0.050 kg and initial velocity v₁ = 9 m / s turned to the right collides with a body of mass m₂ = 0.030 g with unknown initial velocity v₂. After the collision, the two bodies join together and have a final velocity vy = 6 m / s to the right. Using the momentum conservation theorem, find the initial velocity v₂

Answer 1

Suppose two objects of different masses are moving with different velocities in the same direction on a straght-line before collision. After collision, they stick together and move with common (the same) velocity
