A piece of stone m=5kg is attached to a string with length r=80 cm and is rotating in a VERTICAL circular path with constant speed of v=10m/s
a) draw a figure, show forces acting on the stone when it is on the highest and lowest positions. (Don't forget the gravity)
b) draw a free body diagram for each of the two situations
c) use the "radial" Newton's law to find the tension in the string at each of these situations
The forces and the tension of the string is calculated in different situations when a ston is whirled on a vertical circular path.
