Question

A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.16 kg and moves at v = 5.33 m/s. The circular path has a radius of R = 1.13 m

What is the magnitude of the tension in the string when the ball is at the bottom of the circle?

What is the magnitude of the tension in the string when the ball is at the side of the circle?

Answer 1

\[F=\frac{mv^2}{r}\]

Answer 2

centrifugal force

Answer 3

great thank you! thats for when the loop is on its side what about when its at the bottom

Answer 4

that plus the weight of the ball

Answer 5

how do u find the weight again?

Answer 6

\[F=mg\]

Answer 7

great thank you!
