Maximum Trajectory LengthClassical Mechanics Level 4
A ball is thrown at speed \(v\) from zero height on level ground. Let \(\theta\) be the angle at which the ball should be thrown so that the length of the trajectory is maximum. Find \(\theta\) (in degrees).
(Use a calculator or any other computing device in the last step to calculate \(\theta\))
Ignore all viscous and drag forces.
