6.4A Uniform Circular Motion Dynamics HW1.A boy is swinging a marble on a string as seen below. The string breaks at point P, whichpath will the marble follow? Explain your answer.2.A spring scale is attached to a block via a rope that is 1m in length. When the block isnot swinging the scale reads 20N. The block is then displaced as shown and released tofollow a circular path. As the block passes the lowest point the scale reads 35N. Howfast is the block moving at the lowest point?3.The Jungle Boy, mass 45, holds on to a vine that is horizontal. The vine has a length of10m and is hanging over a cliff. If the joy jumps off and swings on the vine. What is thetension in the vine as the boy passes the lowest point while his speed is 12.5m/s?4.A 2-kg pail of water is moving at a constant speed of 9 m/s in a vertical circle of radius0.4 ma.Find the tension force at the top.b.Find the tension force at the bottom.
