Question

A 0.275-kg object is swung in a
vertical circular path on a string 0.850 m
long as in Figure P7.70. (a) What are
the forces acting on the ball at any point
along this path? (b) Draw free-body diagrams
for the ball when it is at the bottom
of the circle and when it is at the
top. (c) If its speed is 5.20 m/s at the top
of the circle, what is the tension in the
string there? (d) If the string breaks when its tension exceeds
22.5 N, what is the maximum speed the object can have at the
bottom before the string breaks?
