The pilot of an aircraft, who is not tied to his seat, can loop a verticle circle in air without falling out at the top of the loop . What is the minimum speed required so that he can successfully negotitate a loop of radius 4 km ? `(g=10 m//s^(2))`

A motor cycle rides in a hollow sphere in a verticle circle of radius 30 m .What will be the minimum speed required so that he does not lose contact with the surface of sphere at the highest point?

A particle of mass 100 g is moving in a vertical circle of radius 2 m The particle is just looping the loop . What is the speed of the particle and tension in the string at the highest point of the circular path ? . (g =10 ms^(-2)) .

You may have seen in a circus a motorcyclist driving in vertical loops inside a ‘death- well’ (a hollow spherical chamber with holes, so the spectators can watch from outside). Explain clearly why the motorcyclist does not drop down when he is at the uppermost point, 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 ?
