During a stunt, a cyclist (considered to be a particle) is undertaking horizontal circles inside a cylindrical well of radius 6.05 m. If the necessary friction coefficient is 0.5, how much minimum speed should the stunt artist maintain ? Mass of artist is 50 kg . If she/ he increses the speed by 20%, how much will the force of friction be ?

During a stunt a cyclist ( considered to be a particle is undertaking horizontal circles inside a cylindrical well of radius 6.05m. If the necessary friction coefficient is 0.5, how much minimum speed should the stunt artist maintain? Mass of the artist is 50kg. If she / he increases the speed by 20% how much will the force of friction be? (Use g = 10ms^2)

A motor cyclist is to undertake horizontal circles inside the cylindrical wall of a well of inner radius 4m . Coefficient of static friction between the tyres and the wall is 0.4. Calculate the minimum speed and frequency necessary to perform this stunt.

A motor cyclist (as a particle ) is undergoing vertical circles inside a sphere of death . The speed of the motorcycle varies between 6m/s and 10 m/s. Calculate diameter of the sphere of death. How much minimum values are possible for these two speeds ?
