1. The problem statement, all variables and given/known data A heavy mallet of Mass M (see Attached file) is dropped and moves through vertical distance y before it hits the top of a tent stake of mass m, driving it into the ground a distance d. Assume that the ground offers a a constant resistance to the motion of the tent stake and mallet, which move together after impact. Show that the combined velocity, vc, of the mallet and the tent stake after impact in terms of the mass of the mallet M, the mass of the stake m and the velocity of the mallet before impact v is given by vc=v/(1+m/M) 2. Relevant equations 3. The attempt at a solution I tried to use the equation; Total momentum before collision = Total momentum after collision but had no success.
