SUMMARY

The discussion centers on a collision problem involving two masses: mass 1 (4.35 kg) moving at an initial velocity of 2 m/s and mass 2 (4.00 kg) at rest. The participant calculated the final velocities post-collision as 0.0838 m/s for mass 1 and 2.08 m/s for mass 2, utilizing both momentum and energy conservation principles. The calculations were confirmed as correct, emphasizing the importance of applying both momentum and energy conservation in collision problems.

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
