SUMMARY

The discussion focuses on the oblique collision of two smooth spheres with masses of 2 kg and 4 kg, where the 2 kg mass comes to rest post-collision. The coefficient of restitution is established at 1/2. Using the conservation of momentum equation, 4x + 2y = 4p + 2(0), where x and y represent the velocities before impact and p is the velocity of the 4 kg mass after impact, participants aim to prove that the spheres were initially moving perpendicularly to each other. Newton's experimental law is applied to relate the velocities before and after the collision.

PREREQUISITES
  • Understanding of conservation of momentum principles
  • Familiarity with the coefficient of restitution in collisions
  • Knowledge of Newton's laws of motion
  • Basic algebra for solving equations involving velocities
NEXT STEPS
  • Study the derivation of the conservation of momentum in two-dimensional collisions
  • Learn about the coefficient of restitution and its implications in elastic and inelastic collisions
  • Explore Newton's laws of motion in the context of collision analysis
  • Practice solving problems involving oblique collisions of masses
USEFUL FOR

Physics students, educators, and anyone interested in understanding the mechanics of collisions and momentum conservation in two-dimensional motion.

two smooth spheres of masses 2kg and 4kg collide obliquely . the 2 kg mass is brought to rest. the coefficient of restitution is 1/2
prove before the impact the spheres were moving in perpendicular directions to each other.

using conservation of momentum. 4x+2y=4p+2(0) where x and y are velocities before impact. p is velocity after impact of 4kg

Newtons experimental law p-0/x-y =-1/2

once i get there velocities in terms of the variables i don't know what to do

anyone?
the velocity in the j direction does not change as its along the i axis
