Calculating Momentum & Energy for M1 & M2 Collision

Click For Summary
SUMMARY

The discussion focuses on calculating momentum and kinetic energy for an elastic collision involving two masses, M1 (200g) and M2 (300g). Participants emphasize the necessity of knowing at least one initial velocity to compute the final velocities (V0, V1, V2) and the corresponding momentum (P0, P1, P2) and kinetic energy (KE0, KE1, KE2). The key equations referenced include p = mv for momentum and KE = 0.5mv² for kinetic energy. Without additional velocity data, participants agree that completing the calculations is not feasible.

PREREQUISITES
  • Understanding of elastic collision principles
  • Familiarity with momentum calculations using p = mv
  • Knowledge of kinetic energy calculations using KE = 0.5mv²
  • Basic algebra for solving equations
NEXT STEPS
  • Learn how to derive final velocities in elastic collisions
  • Study the conservation of momentum in multi-body collisions
  • Explore experimental methods for measuring velocities in collisions
  • Investigate the relationship between kinetic energy and momentum in elastic collisions
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding the principles of momentum and energy in collisions.

Homework Statement



3. Tabulate the data for your measurements. Include all the measured constants you used for calculations. Show in detail the calculations of V0, V1, and V2 for an elastic collision with
M1 = 200g and M2 = 300g.

4. Tabulate the data for momentum and kinetic energy (KE) and show in detail the
calculations of P0, P1, and P2 as well as KE0, KE1, and KE2, for an elastic collision with
M1 = 200g and M2 = 300g.

Homework Equations


Any equations that deal with momentum and energy like p=mv and .5mv^2=e


The Attempt at a Solution



Ok, for a start is #3 even possible? All you know is that m2 is at rest. I think you need to know at least one more velocity before you can find out the other values right? I think the best you can do is solve v0, v1 and v2 as part of an equation. But then if you can't solve it how do you do #4?

Thanks :)

It all depends on what you measured. We cannot answer your question unless you tell us exactly what you did and how.
