A motor cyclist rides in a vertical circle in a hollow sphere of 3m. Find the minimum speed required so that he does not lose contact while the sphere at the highest point.

Motor cylist rides in the verticle circle in 'well of death' sphere of radius 9m. What will be speed required so that he does not lose contact at the highest point?

A motorcyclist rides in vertical circles in a hollow sphere of radius 5 m. Find the required minimum speed and minimum angular speed, so that he does not lose contact with the sphere at the highest point .

A stone is tied to a weightless string and revolved in a vertical circle of radius 5 m . What should be the minimum speed of the stone at the highest point of the circle so that the string does not slack ? What should be the speed of the stone at the lowest point of vertical circle ? Take g = 9.8 ms^(2) .

A bucket full of water is rotated in vertical circle of radius 20 m. The minimum speed that the bucket should have so that water will not fall when it is at the highest point is:

A bucket tied at the end of a 1.6m long string is whirled in a verticle circle with constant speed. What should be the minimum speed so that the water from the bucket does not spill, when the bucket is at the highest position (Takeg=10m//s^(2))
