Answer:
[tex]h_m=25.8\ m[/tex]
Explanation:
Vertical Launch Upwards
In a vertical launch upwards, an object is launched vertically up without taking into consideration friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:
[tex]\displaystyle h_m=\frac{v_o^2}{2g}[/tex]
The tennis ball was thrown straight up with a speed of v0=22.5 m/s. The acceleration of gravity is g=9.81\ m/s^2, thus:
[tex]\displaystyle h_m=\frac{22.5^2}{2\cdot 9.81}[/tex]
[tex]\mathbf{h_m=25.8\ m}[/tex]
