Question

A carnival event known as well of death consists of a large vertical cylinder inside which usuallya stunt motorcyclist rides in horizontal circles. Show that the minimum speed necessary to keep therider from falling is given by u =2√rg/ u s ,in usual notations.​

Answer 1

Answer:

The forces exerted on the rider are 1. the normal force → N N→ exerted by the wall, directed radially inward, is the centripetal force, 2. the upward frictional force → f s fs→ exerted by the wall, since the motorcycle has a tendency to slide down, 3. the downward gravitational force m → g g→. Well of death, with the motorcyclist treated as a point mass at the wall of the well Where m is the mass of the rider and v is the speed of the motorcyclist. For the rider not to fall, → f s fs→ must balance → g g→. which is the required expression.Read more on Sarthaks.com - https://www.sarthaks.com/2345962/a-carnival-event-known-as-a-well-of-death-consists-of-a-large-vertical-cylinder-inside
