5: Wave on a hanging string (8 points) A heavy metallic cable of length L and mass m hangs from the ceiling. (a) (2 points) If we define the bottom of the cable to be where y = 0 and the ceiling to be y = L, what's the tension in the cable at a point y along the cable? (Hint: How much weight is it supporting?) (b) (2 points) What's the speed of a vibrational wave traveling along the...

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...

An object is hanging by a string from the ceiling of an elevator. The elevator is moving upward with a constant speed. What is the magnitude of the tension in the string? The magnitude of the tension in the string is equal to the magnitude of the weight of the object. The magnitude of the tension in the string is less than the magnitude of the weight of the object. The tension in the string cannot be determined without knowing...

Two particles of m_1 and m_2 are connected by a light, inextensible string of total of mass length L, which passes through a smooth hole in a smooth horizontal table. The mass m_2 is suspended below the table, and the mass m_1 moves in a circular motion on the table with an initial distance R_0 from the hole. A gravitational field g acts on this system. The mass m_1 starts out with speed v_0 on the table...
