You are working as an assistant to a landscape architect, who is planning an artificial waterfall in a city park. Water flowing at 1.83 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 3.10 m high, and from there it will fall into a pool (see the figure below). Calculate the space behind the waterfall to determine if it will be wide enough for a 1.0 m pedestrian walkway.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
