Question

A 35.0 g ball at the end of a string is swung in a vertical circle with a radius of 35.0 cm. The rotational velocity is 212.0 cm/s.
(a)Find the tension (in N) in the string at the top of the circle.

(b)Find the tension (in N) in the string at the bottom of the circle.

Answer 1

After a mishap, an 82.8 kg circus performer clings to a trapeze, which is being pulled to the side by another circus artist, as shown here.
(angle for T1 = 15)
(angle for T2 = 10)
Calculate the tension (in N) in the first rope,T1, if the person is momentarily motionless. (Enter the magnitude.)

Calculate the tension (in N) in the second rope, T2, if the person is momentarily motionless. (Enter the magnitude.)

Answer 2

A 35.0 g ball at the end of a string is swung in a vertical circle with a radius of 35.0 cm. The rotational velocity is 212.0 cm/s.
(a)Find the tension (in N) in the string at the top of the circle.

Tension at top: mv^2/r-mg
Tension at bottom: mv^2/r+mg

I can't visualize the second problem without the figure.
