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

Step 1 </p>

We need to find out the initial speed of the shot put which throws at a distance with an angle and which is released from a height above the ground.

The vertical distance travelled by the ball from the height 2.10 m is

Step 2</p>

To find out the total vertical distance we need to add the above value we got for the vertical distance and the length between ground and the released point.
