Elastic Collisions solving for velocity any help?

Click For Summary
The discussion focuses on solving for final velocities (m1v1f and m2v2f) in elastic collisions using the equations for conservation of momentum and kinetic energy. The user presents the equations: 1/2m1v1,0 = 1/2m1v1f^2 + 1/2m2v2f^2 and m1v1,0 = m1v1f + m2v2f. A suggestion is made to simplify the problem by dividing all terms by m1 and squaring the second equation to facilitate solving for the final velocities. The conversation emphasizes the mathematical approach to resolving these equations. Understanding these principles is crucial for accurately calculating outcomes in elastic collisions.

1/2m1v1,o=1/2m1v1f^2 +1/2m2v2f^2
and
m1v1,0= m1v1f + m2v2f

any idea on how to solve for m1v1f and m2v2f

Try dividing everything by m1, and squaring the second equation. :wink:
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
