Answer:
θ = 56.09°
Explanation:
Given that
h = 8.5 ft
speed ,u= 28 ft/s
We know that acceleration due to gravity g
g= 32.2 ft/s²
The maximum height h is given as
[tex]h=\dfrac{u^2sin^2\theta}{2g}[/tex]
Now by putting the values
[tex]8.5=\dfrac{28^2sin^2\theta}{2\times 32.2}[/tex]
[tex]sin^2\theta=0.69 [/tex]
[tex]sin\theta=0.83 [/tex]
θ = 56.09°
Therefore the angle will be θ = 56.09°
