A bucket is swung on a rope in a vertical circle as shown in the diagram below. The bucket has a mass of 1.5 kg, the radius of circular motion is 1.2 m, and it is being spun at a rate of 45 revolutions per min (RPM) what is the tension of the rope at position A (bottom) and position B (top)?
the diagram is just a circle that points out the top, bottom and radius of the circle

drwls,
(1) Calculate the speed V of the bucket from the rpm and the value of R.
(2) At the top, T = M*[(V^2/R) g]
At the bottom, T = M*[(V^2/R) + g] 
PHYSICS 
Needs an Answer,
How do you calculate the speed V of the bucket?

PHYSICS 
Rewati,
v=sqrt(R*g)
as, w=v/R (rad/s)
