a. minimum velocity is important at the top of the swing.
centripetalforce>mg
m v^2/r>mg
v>sqrt you do it.
b. tension=mv^2/r-mg
c. tension=mv^2/r + mg
Include units with all of your answers.
A 1.84 kg bucket full of water is attached to a 0.76 m long string.
a. If you swing the bucket in a vertical circle, what is the minimum speed you must swing it so the water does not fall out at the top of the circle?
b. What is the magnitude of the tension in the string at the top of the circle if you are swinging it at 3.55 m/s?
c. What is the magnitude of the tension in the string at the bottom of the circle if you are swinging it at 3.37 m/s?
