Equation [3], conservation of momentum, is used to find the initial velocity of the ball, Vb. The velocity of the pendulum-ball, Vf, is taken from the velocity v found in question 1 . The pendulum, mp, is initially at rest, and mb is the mass of the ball. Using equation [3], determine an equation to solve for the velocity of the ball, Vb, in terms of mb, m and Vf
