Solving the trigonometric equation, it is found that it takes 40 seconds to complete one turn.
The height is modeled by:

The initial height is
, hence, one turn is completed when h(t) = 15.




The length of one turn is of
, and
, hence, the solution is found according to:



It takes 40 seconds to complete one turn.
