My kids came up with a form of tether ball where they attached a ball to a string and let it swing around the role. Then one of them had the clever idea to attach another string to the ball to limit how high it could go. The mass of the ball is 2 kg while each piece of string is 125 cm long. The pole is 2 m high. The tension in the first (top) string is 80 N.
A) Find the tension in the other string.
B) How many times does the ball swing around each minute?
C) IF the tension in the second string were to approach zero, how many times per minutes does the ball go around the pole?
