1. The problem statement, all variables and given/known data Show how to simplify (mBvB2 - mBvC2 - mCvC2)/(mBvB2) to mC/(mC + mB) 2. Relevant equations vB is not equal to vC. vB = muzzle speed of a bullet = unknown value vC = speed of the clay block after it is hit by the bullet = unknown value vB = ((2gh)0.5(mB + mC))/mB vC = (2gh)0.5 g = gravitational acceleration h = unkown height mB is not equal to mC mB is the mass of a bullet. mB is unkown though mC is the mass of a clay block. mC is also unkown 3. The attempt at a solution I have tried many different methods, but I still cannot show how to simplify the above equation Please Help!
