A high-school pitcher is employing a ballistic pendulum to determine the speed of his fastball. A 3.3-kg lump of clay is suspended from a cord 2.0-m long. When the pitcher throws his fastball aimed at the clay, the ball becomes embedded in the clay and the two swing up to a maximum height of 0.11 m. If the mass of the baseball is 0.21 kg, find the speed of the pitch. Please provide step by step method to solving the problem.
