Inelastic Collisions: Calculating Momentum

Click For Summary
SUMMARY

The discussion focuses on calculating the momentum of two clay balls involved in a completely inelastic collision. Each ball has a mass of 0.23 kg, with one traveling at 5.6 m/s and the other at 7.8 m/s, moving perpendicularly to each other. The final velocity of the combined mass is determined using the equation vf = (m1vi1 + m2vi2) / (m1 + m2), which requires splitting the momentum into x and y components to find the resultant momentum magnitude after the collision.

PREREQUISITES
  • Understanding of momentum and its conservation principles

Homework Statement




Two clay balls of the same mass stick together in an completely inelastic collision. Before the collision, one travels at 5.6 m/s and the other at 7.8 m/s, and their paths of motion are perpendicular. If the mass of each ball is 0.23 kg, what is the magnitude of the momentum of the combined balls after the collision?



Homework Equations



vf= (m1vi1 + m2vi2) / m1 + m2
