Can someone help me with this:
For a completely inelastic collision, the fractional change in kinetic energy can be found as a function of the masses of the projectile and target carts only. Show that the fractional change in kinetic energy is given by:
[KE(final) - KE(initial)] / KE(initial) = -M / (m + M)
I know that KE = 1/2 mvsquared
but I can't seem to cancel v out to get -M / (m + M)
