Homework Equations
W = ΔKE
W = KEf-KEi
The Attempt at a Solution
W = .5mvf2 -.5mvi2
I know that final KE for A is 4 times the KE of B because for A ... KEf = 1/2 m (2v)^2
4KE = 1/2 m v ^2 for A
I don't know what initial KE for both of them are... so how do i know if that had equal losses of energy to friction??
