Homework Statement
A stationary object with mass mb is struck head-on by an object with mass ma that is moving initially at speed v0.
If the collision is elastic, what percentage of the original energy does each object have after the collision?
KA2/K1 = ?
KB2/K1 = ?
Homework Equations
K1 = 1/2mav1a^2 + 1/2mbv1b^2
K2 = 1/2mav2a^2 + 1/2mbv2b^2
The Attempt at a Solution
K1/K2A = (1/2mav1a^2 + 1/2mbv1b^2)/(1/2mav2a^2)
= v1a^2/v2a^2 + mbv1b^2/mav2a^2
I'm not sure how to proceed from here and get a percentage.
any help is appreciated.
