A mass is attached to one end of a massless string, the other end of which is attached to a fixed support. The mass swings around in a vertical circle as shown in Fig. 5.36. Assuming that the mass has the minimum speed necessary at the top of the circle to keep the string from going slack, at what location should you cut the string so that the resulting projectile motion of the mass has its maximum height located directly above the center of the circle?

Conical Pendulum A mass attached at the end of a massless string swings around in a horizontal circle (the string sweeps out a cone). Let θ be the angle the string makes with the vertical, l be the length of the string, h is the vertical height of the string, and r is the radius of the circle. So, l is the hypotenuse of a right triangle with h and r as legs, and θ as the upper angle. The...
5) A mass m is connected to one end of a massless string of length L. The other end of the string is tied to a tall vertical pole of height H (much taller than L). The string is wound around the pole so that each wrap makes a small circle of the string and the mass touches the top of the pole. The mass is let go and the string begins to unwind. What is the angle o that...
One end of a 0.80 m string is fixed, the other end is attached to a 2.0-kg stone. The stone swings in a vertical circle, passing the bottom point at 10 m/s. What is the radial acceleration of the stone at the top of the circle? (Ans: 86 m/s2)

A 0.5 KG mass attached to the end of a string swings in a vertical circle of radius 2 m. When the mass is at the lowest point of a circle, the speed of the mass is 12 m/s. The magnitude of the force in (N) of the string on the mass at this position is approximately?
A mass m = 4 kg hangs on the end of a massless rope L = 1.91 m long. The pendulum is held horizontal and released from rest. 1) How fast is the mass moving at the bottom of its path? m/s 2) What is the magnitude of the tension in the string at the bottom of the path? N 3) If the maximum tension the string can take without breaking is Tmax = 337 N, what is the maximum...
A rock of mass m = 0.97 kg is attached to a massless string of length L = 0.71 m. The rock is swung in a vertical circle faster and faster up to a speed of v = 2.4 m/s, at which time the string breaks. What is the magnitude of the tension, in newtons, at which the string breaks?
A mass M = 4 kg attached to a string of length L = 2.0 m swings in a horizontal circle with a speed V. The string maintains a constant angle 0 = 44.1 degrees with the vertical line through the pivot point as it swings. What is the speed V required to make this motion possible?
A mass m0.2kg is attached to the end of a massless string. The mass is rotating in a circular orbit of radius r 0.6m on a frictionless table with period T 1.2s. The string is pulled slowly downwards 0.2m through hole in the table. φ What is the new period of circular orbit for mass m? (ii) How much work is done on the mass?
