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?

Object rotating on a string of changing length. A small mass m attached to the end of a string revolves in a circle on a friction-less tabletop. The other end of the string passes through a hole in the table. Initially the mass revolves with a speed 2.4 m/s in a circle of radius 0.80 m. The string is then pulled slowly through the hole so that the radius i reduced to 0.48 m. The final speed is 4.0 m/s...

A 0.2 kg ball is attached to the end of a 0.8 m string so that it can swing as a pendulum. The string will break if the tension exceeds 5 N (where is it most likely to break?). Calculate the maximum height from which the ball can be dropped without breaking the string.

A pendulum consists of a 2.5-kg bob attached to a light 1.2 m-long string. While hanging at rest with the string vertical, the bob is struck a sharp horizontal blow, giving it a horizontal velocity of 3m/s. At the instant the string makes an angle of 38 degree with the vertical, what is The speed, The tension in the string? What is the angle of the string with the vertical when the bob reaches its greatest

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...

One end of a cord is fixed and
a small 0.550-kg object is attached to the other end, where it
swings in a section of a vertical circle of radius 1.00 m, as shown
in the figure below. When θ = 30.0°, the speed of the object is
6.50 m/s.

A small mass m attached to the end of a string revolves in a circle on a frictionless tabletop. The other end of the string passes through a hole in the table (Fig. 8-62). Initially, the mass revolves with a speed vi = 2.4 m/s in a circle of radius ri =0.80 m. The string is then pulled slowly through the hole so that the radius is reduced to r2 0.48 m. What is the speed, 2, of the m...

4. A small object of mass M is swinging around in a vertical circle held by a massless string of length L, attached to a pivot, as shown. Given that the speed of the mass at the bottom of the circle is Vo, find the tension in the string when the mass is at an angle (theta) with respect to the vertical (see figure) Pivot M
