Question

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 $38.0^\circ$ above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at $45^\circ$ when air resistance is neglected, the actual angle to achieve maximum range is smaller [when air resistance occurs]; thus, $38^\circ$ will give a longer range than in the shot put.)

$15.0 \textrm{ m/s}$
