A lead fishing weight of mass 0.20 kg is tied to a fishing line that is 0.50 m long. The weight is then whirled in a vertical circle. The finishing line will break if its tension exceeds 100.0 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 10.0 kg ball is attached to a massless rope that is 1.30 m long. The rope is pushed to 45 degrees from the vertical and released from rest. Ignore the rotation of the ball as the rope swings, and this does not appreciably affect the dymanics. What is the potential energy of the ball with reference to its lowest position? B) How fast will the ball be moving at the bottom of the swing? and B) How long does...
