Motion in Verticle Circle: Force and Tension.

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

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

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)

The forces acting on the stone are the weight of the stone ...

Solution Summary

The forces and the tension of the string is calculated in different situations when a ston is whirled on a vertical circular path.

Motion on a vertical circle.

This problem is a three-parter. Here we go:

A stunt man whose mass is 72.7 kg swings from the end of a 4.51 m long rope along the arc of a vertical circle.

1.) Assuming he starts from rest when the rope is horizontal, find the tension in the rope that is required to make him follow his circular path at the beginning of his motion.

2.) Find the tension in the rope of at a height of 1.60 m above the bottom of the circular arc.

3.) Find the tension in that rope at the bottom of his arc.

I'd be grateful for any help. Thank you so much.
