Question
1. Pick one of the collisions from the data table. Show the calculation for determining the total initial momentum of the system for that collision.
Momentum is the product of velocity and mass:
p = mv
The total initial momentum of the system equals the sum of the momentums of Spheres 1 and 2 before the collision. Be sure to include a negative sign on the velocity as appropriate.
pinitial = (m1v1)initial + (m2v2)initial
The total final momentum of the system equals the sum of the momentums of Spheres 1 and 2 after the collision.
pfinal = (m1v1)final + (m2v2)final
Collision Number
Mass Sphere 1 (kg)
Mass Sphere 2 (kg)
Initial Velocity Sphere 1 (m/s)
Initial Velocity Sphere 2 (m/s)
Final Velocity Sphere 1 (m/s)
Final Velocity Sphere 2 (m/s)

3. Analyze the final results reported in the last data table. How does the momentum of the system after the collision compare to the momentum of the system before the collision? Use the data to support your claim.

Explanation / Answer
I took collision number 1 to solve this problem
The initial momentum of spheres before collision is
pinitial = (m1v1)initial + (m2v2)initial
= 2kg ( 0.5) + 1kg ( 0)
= 1 kg m/s
the final momentum of the collision is
pfinal = (m1v1)final + (m2v2)final
= 2kg ( 0.17) + 1(0.67)
=1.0 kg m/s
