In 2007, michael carter (u. s.) set a world record in the shot put with a throw of 24.77 m. what was the initial speed of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0Âș above the horizontal? (although the maximum distance for a projectile on level ground is achieved at 45Âș when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus, 38Âș will give a longer range than 45Âș in the shot put.)
