Question

A ball of mass m = 0.275kg swings in a
vertical circular path on a string L= 0.85m
long. If its speed is 5.2m/s at the top of the
circle, what is the tension in the string
there?
If the string breaks when its tension
exceeds 22.5N, what is the maximum the
L
ball can have at the bottom before that
m
happens?

A tennis ball connected to a string is spun counterclockwise around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.16 kg and moves at speed v = 2.4 m/s. The circular path has a radius of R = 0.26 m. The ball is at the bottom of the circle as shown. What is the magnitude of the tension force on the ball at this instant, in Newtons? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
