A 700-g rock is attached to a half-meter (massless) string and is spun on the other end on vertical plane.
The rock makes a complete revolution every 0.21 seconds. What is the tension of the string at the top of
the circular trajectory, and at the bottom of the circular trajectory? What is the difference in total energy
1.
at the top and bottom of the trajectory?
