Need Check on Collision Question

[tachu101]

Homework Statement

A mass 1 is moving at a constant velocity and collides with a ball of mass 2 that is at rest. What are the final velocities of the masses and the direction of the velocity?

Mass 1 = 4.35kg
Initial Velocity of mass 1= 2m/s
Mass 2 = 4.00
Initial Velocity of mass 2 = 0 m/s

The Attempt at a Solution

I calculated .0838 m/s for the mass 1 and 2.08 m/s for mass 2. I used momentum to calculate the answers. Can anyone check this?

That's right. But you didn't just use momentum, did you? You used energy as well.

yes I used both together. Thanks
