02a. A stone with a mass of 0.567 kg is tied to the end of a
cord that is 1:02 m long and swung in a horizontal
circle. The stone takes 0.736 seconds to make one
revolution. Calculate the speed of the stone.
Response:
02b. Calculate the amount of tension in the cord.
Response:
03. A 0.152 kg stopper is tied to the end of a string that is
0.842 m long and swung in a VERTICAL circle at a
constant speed. If a constant speed of 8.42 m/s is
nintnined what is the tension in the cord at the top
