(II) One end of a horizontal string of linear density 6.6 × 10 −4 kg/m is attached to a small-amplitude mechanical 120-Hz oscillator. The string passes over a pulley, a distance ℓ = 1.50 m away, and weights are hung from this end, Fig. 15-37. What mass m must lie hung from this end of the string to produce ( a ) one loop, ( b ) two loops, and ( c ) five loops of a standing wave? Assume the string at the oscillator is a node, which is nearly true. FIGURE 15-37 Problem 52 and 53.

A string of mass 2.50 kg is under a tension of 200 N. The length of the stretched string is 20.0 m. If the transverse jerk is struck at one end of the string, how long does the disturbance take to reach the other end?
the acceleration a(t) of a particle undergoing SHM is graphed in Fig. 15-19. Separate multiple points with a space or comma.
(a) Which of the labeled point(s) correspond(s) to the particle at the negative displacement amplitude?
(b) At point 4, is the velocity of the particle positive, negative or zero
(c) At point 5, is the particle at what position
In Fig. 15-28, a spring–blocksystem is put into SHM in two experiments. In the first, the block ispulled from the equilibrium positionthrough a displacement d1 and thenreleased. In the second, it is pulledfrom the equilibrium positionthrough a greater displacement d2 and then released. Are the(a) amplitude, (b) period, (c) frequency, (d) maximum kinetic energy, and (e) maximum potential energy in the second experimentgreater than, less than, or the same as those in the first experiment?
