A 3.8 kg block is attached to a vertical spring with spring constant 18 N/m. At one instant, the block is at 5.4 cm above equilibrium and has velocity 30 cm/s. 8.0 m x = 0 A) Determine the amplitude of the oscillation. B) One end of a 60 g string is tied to the block and the other end to a pole as shown in the above figure. The string is 8.0 m long. The oscillation of the block produces a wave of wavelength 0.6 m travels in the +x direction along the sting. What is the tension of the string? C) At x = 0.80 m and t = 0, D(0.8,0) is a crest. Write a complete expression (in terms of sine function) for the displacement of the string as a function of position x and t in Sluni %3D ww
