The angle at which a projectile must be fired to cover maximum range is
A
30°
B
45°
C
60°
D
90°
Verified Correct Answer: B.
Physical Principles & Numerical Solution
The formula is \(\frac{v^{2}sin2\theta}{g}\)
And the sine graph is highest at 1 with its inverse as 90^\circ. Hence, \(2\theta\) = 90^\circ
\(\theta\) = 45^\circ
