Youmay have seen in a circus a motorcyclist driving in vertical loopsinside a ‘death-well’ (a hollow spherical chamber withholes, so the spectators can watch from outside). Explain clearly whythe motorcyclist does not drop down when he is at the uppermostpoint, with no support from below. What is the minimum speed requiredat the uppermost position to perform a vertical loop if the radius ofthe chamber is 25 m?
