Step-by-step derivation from centripetal force = gravitational force. Many solution guides also include algebraic manipulation tips for inverse-square law problems.
For a projectile launched at 30° with 20 m/s, the time to max height = (v sinθ)/g. A good solution will warn students not to use the same time for horizontal range without checking if the landing height is the same as launch height.
