Throw off a Cliff

Two-dimensional display of the trajectory of an object thrown from a cliff into the sea. Parameters of the trajectory that you can vary are the cliff height , the initial velocity , and the initial angle .

DETAILS

The trajectory of the object is given by
.
For simplicity, set .
The main goal of the Demonstration is to explore the range of the trajectory, that is, the maximum coordinate that can be achieved with a given height and a given velocity . It is well-known that in the case of a ground-to-ground throw () the range is maximized for , as shown by the snapshots. For this condition no longer holds and the general expression for the range is given by
,
for which the maximal range becomes
.
