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 1.0 kg object is attached to one end of a 1.25 m long string. The other end of the string is fixed. The object is released from rest when the string is horizontal falls to a vertical 90-degree angle. What is the speed of the object as the lowest point along the path (when the string is vertical)? What is the value of the tension in the string at the lowest point? What is the work done by the...

Problem 5 A man is swinging an object, attached to a string, in a circle over his head (see the sketches). Side view Top view (a) Draw a free-body diagram for the object. Notice the string is not drawn horizontal in the "side view" diagram above. Why is that? (b) If the mass of the object is 1 kg, what is the vertical component of the tension? (c) If the object makes 3 turns per second, and the radius of...

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 ball moves in a vertical circle attached to a light string of length 0.3 m fixed at its center. Assume that the only force acting on the ball are its weight and the tension of the string. Determine the minimum speed the ball must have, when the string makes a 90 degree angle with the vertical, so as to complete the circle by reaching the top.

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...
