A Baseball Pitcher Is Employing a Ballistic Pendulum to Determine $\text { 3.3-kg }$

A baseball pitcher is employing a ballistic pendulum to determine the speed of his fastball. A $\text { 3.3-kg }$ lump of clay is suspended from a cord 2.0 m long. When the pitcher throws his fastball aimed directly at the clay, the ball suddenly becomes embedded in the clay and the two swing up to a maximum height of 0.080 m. If the mass of the baseball is 0.21 kg, find the speed of the pitched ball.
