Question:
A mass M at the end of a string is being rapidly rotated on a horizontal circle, as shown. When the string breaks, the object's speed is v and the radius of the circular path is R with a height h above the ground. Neglect air friction.
a Express all answers in terms of h v and g and determine the following:
i The time required for the object to hit the ground after the string breaks.
ii The horizontal distance traveled by the object from the moment the string breaks to when it hits the ground.
iii. The speed of the object immediately before hitting the ground.
b Draw and label all the forces acting on the object when it is in the position shown in the diagram above.
c Determine the tension in the string just before it breaks, expressing it in terms of M R v and g
