A stone thrown from the ground reaches a maximum height of 40 mm falls on to the ground at a distance of 100 m from the point of projection. Trace the path of the stone in space.

A stone is thrown from a 7 m high building, and at its highest flight the stone just crosses a 14 m high palm tree. Trace the path of the stone till it touches the ground. The distance between the building and the palm tree is 4 m.

The distance between the vertices of two branches of a hyperbola is 60 mm. The asymptotes of the curve are inclined at 600 to the transverse axis. Construct the hyperbola.
