Kinetic friction problems and solutions

Web5 nov. 2024 · If we then divide Eq. 1 by Eq. 2 and perform some cancelations we will find: v1i + v1f = v2f + v2i. (Eq. 3) We can solve for v1f as: v1f = v2f + v2i − v1i. (Eq. 4) At this point we see that v2f is still an unknown variable. So we can fix this by plugging Eq. 4 into our initial conservation of momentum equation.
