A ball with a mass of # 6 kg# is rolling at #2 m/s# and elastically collides with a resting ball with a mass of # 8 kg#. What are the post-collision velocities of the balls?
1 Answer
The post collision velocities of the balls are
Explanation:
As the collision is elastic, there is conservation of momentum and conservation of kinetic energy
The mass the first ball is
The velocity of the first ball before the collision is
The mass of the second ball is
The velocity of the second ball before the collision is
The velocity of the first ball after the collision is
The velocity of the second ball after the collision is
From equations
