A bucket containing water is whirled in a vertical circle at arms length. Find the minimum speed at top to ensure that no water spills out. Also find corresponding angular speed.

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))

A bucket full of water is rotated in a vertical circle of radius R. If the water does not spill out, then the speed of the bucket at the topmost point will be

A body of mass 2 kg is attached to a cord and whirled in a vertical circle of radius 2 m. The minimum speed at the bottom of the circle so that the cord will not slacken when the body rounds the top of the circle will be

A stone is tied to a string of length L and is whirled in a vertical circle,with the other end of the string at the centre. At a certain instant of time, the stone is at its lowest position and has a speed u. The magnitude of change in velocity as it reaches a horizontal position is

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.

A bucket full of water is tied at the end of rope of length 1.6 m. It is rotated in vertical circle with constant speed around the other end. What should be the minimum speed of bucket so that water does not spill out at the highest position of the circle ?

A 1kg stone tied at the end of 1 m long string is whirled in a vertical circle with constant speed of 5m/s. If the tension in string is 20N, then find the position of stone.
