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 at the top and bottom of the trajectory?

One end of a cord is fixed and a small 0.400-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.50 m, as shown in the figure below. When θ = 23.0°, the speed of the object is 5.50 m/s. An object is swinging to the right and upward from the end of a cord attached to a horizontal surface.

A person picks up an iron ball on a rope and starts to spin it around them. The person does 500 J of work to get the mass spinning. While spinning, the person steps onto ice (take friction out of the equation). The result is both the mass and the person are spinning around the same point in space (the mass is circling faster on a larger radius and the man is circling slower on a smaller radius). There is a point between the masses that is stationary. The iron ball has a mass of m = 10 kg. The person has a mass of M = 80 kg. 3 vb Point that masses rotate around M Vp When the person lets go of the rope, how fast will the person move and how fast will the ball move?
A ball of mass 2.3 kg, at one end of a string of length L=4.5 m, rotates in a vertical circle just fast enough to prevent the string from going slack at the top of the circle.
