Chapter 6, Problem 11P
A lead fishing weight of mass 0.2 kg is tied to a fishing line that is 0.5 m long. The weight is then whirled in a vertical circle. The fishing line will break if its tension exceeds 100 N. (a) If the weight is whirled at higher and higher speeds, at what point in the vertical circle will the string break (top, bottom, or random position)? (b) At what speed will the string break?

A ball of unknown mass m is suspended on
a light string of length L from the ceiling.
This ball is then put into motion so that it
rotates in a horizontal circle with a rotation
rate of w (in rad/s). Notice that the string
makes an angle of 0 with respect to the
vertical during this motion. If the ball
moved at twice its first rotation rate, find
the new angle the string would make with
respect to the vertical.
