Trajectory of a dart launched from a cliff of height H.
A launcher positioned at the top of a vertical cliff of height \(H\) fires a small dart with an initial speed \(v_0\) at an angle \(\theta\) above the horizontal. The dart travels through the air under the influence of gravity alone with acceleration of magnitude \(g\) and lands on the flat, level valley floor below. Which of the following expressions represents the total time of flight of the dart from launch until it reaches the valley floor?
