A string is set up as shown. One end of the string is attached to an oscillator (which oscillates up and down}. The rest of the string is strung over a frictionless pulley. and a weight with mass m = 4 kg hangs from the other end. From the oscillator to the pulley. the length of the string is L = 2.0 Hi. In this setup. the pulley acts as a xed end for wave reections. oscillator I' L >I (a) The oscillator is driving the string's motion with frequency f1 = 25 Hz, the lowest frequency to create a standing wave in the string. What is the waves speed? (h) What is the magnitude of the tension in the string? (c) If the full length of the string {L+ distance hanging over the pulley) is 2.5 m, what is the mass of the string? (d) Now assume that the oscillator semis a single wave pulse with height 4 cm. which can be described by the general equation of motion. y(ur,t) = Asin(k1- Lat); What is the specic equation of motion fer this scenario? [Hintz What are your values for A, it. w?] (e) What are the expressions for the speed and acceleration of particles on the string? (f) What are the maximum speed and acoeleration for a particle on the string
