## Homework Statement

A 0.159kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.870m/s . It has a head-on collision with a 0.310kg glider that is moving to the left with a speed of 2.15m/s . Suppose the collision is elastic.

a) Find the magnitude of the final velocity of the 0.159kg glider.

b) Find the magnitude of the final velocity of the 0.310kg glider.

## Homework Equations

## The Attempt at a Solution

I know that both the kinetic energy and the momentum is preserved, and I have "constructed" both the equations, but I can't get the right answer!

Here are my previous answers (which were wrong):

Part A:

2.1752

1.7161

1.1262

0.4295

Part B:

0.5899

0.4295

0.2

Thanks!
