Ball 1 has a mass of 0.1 kg and is moving with a speed of 2.5 m/s. It collides head-on with ball 2, which has a mass of 0.3 kg ball and is initially moving toward ball 1 with a speed of 0.75 m/s. Assume a perfectly elastic collision. Calculate the velocities of the two balls after their collision and the total change in the momentum of the system. Be careful with your coordinate system in your math! Give your answers to 2 decimal places (for example, if you get that ball 1 ends up with a speed of 5.12 m/s in the negative direction you would type -5.12). You do not need to include units.

What is the velocity of ball 1?

What is the velocity of ball 2?

What is the total change in momentum of the system?

Homework Answers

Answer #1

Formulae used to find v1 and v2 (Final velocitie of Ball 1 and Ball2 are mentioned in the solution).

And due to perfectly elastic collision the change in momentum of the system in zero because momentum is conserved in the perfectly elastic collision.
