You may have seen in a circus a motorcyclist driving in verttical loops inside a 'deathwell (a hollow spherical chamber with holes, so the spectators can watch from outside). Explatn clearly why the motorcyclist does not drop down when he is at the uppermost potnt, with no support from below. What is the minimum speed required at the uppermost position to perform a vertical loop if the radius of the chamber is $25 \;m ?$
