Answer :
Answer:
The smallest of those two angles is 20°
Explanation:
Here , v = 30m/s
range = 59m
Range =[tex]\frac{u^2sin2\theta}{g}[/tex]
59 =[tex]\frac{30\times30\times sin2\theta}{9.8}[/tex]
[tex]sin2\theta=\frac{59\times9.8}{30\times30}[/tex]
[tex]2\theta=40[/tex]°
[tex]\theta=[/tex] 20° (since 90° -20°= 70°)
Therefore , the two angles are 20° and 70°
Among the both , the smallest angle is 20°
