A pendulum consists of a 2.0 kg stone swinging on a 4.0 m string of negligible mass. The stone has a speed of 8 m/s when it passes its lowest point. (a) What is the speed when the string is at 60° to the vertical? (b) What is the greatest angle with the vertical that the string will reach during the stone's motion? (c) If the potential energy of the pendulum- Earth system is taken to be zero at the...

Conservation of Energy A simple pendulum consists of an object suspended by a string. The object is assumed to be a particle. The string, with its top end fixed, has negligible mass and does not stretch. In the absence of air friction, the system oscillates by swinging back and forth in a vertical plane. If the string is 1.50 m long and makes an initial angle of 34.5° with the vertical, calculate the speed of the particle at the following...

Pendulum. A small rock with mass 0.10 kg is fastened to a massless string with length 0.84 m to form a pendulum. The pendulum is swinging so as to make a maximum angle of 45° with the vertical. Air resistance is negligible (a) What is the speed of the rock when the string passes through the vertical position? m/s (b) What is the tension in the string when it makes an angle of 45° with the vertical? (c) What is...

A 1.2 kg mass in placed on the end of a 1.4 m string. One end of the string is fixed, creating a simple pendulum. The mass is pulled to the side so that the string makes an angle of 8◦ with respect to the vertical and released from point A at t = 0. (a) What is the angular frequency of the system? (b) What is the mechanical energy of the pendulum? (c) What is the maximum linear speed...

A pendulum consists of a 1.7-kg bob attached to a light 2.6-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 5.0 m/s. At the instant the string makes an angle of 28° with the vertical, calculate the following (a) the speed m/s (b) the gravitational potential energy (relative to its value is at the lowest point) (c) the tension in the string? (d) What is...

A pendulum consists of a 2.2-kg bob attached to a light 2.0-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 4.5 m/s. At the instant the string makes an angle of 27 degree with the vertical, calculate the following: (a) the speed m/s (b) the gravitational potential energy (relative to its value is at the lowest point) J (c) the tension in the string? N...
