The type of rubber band used inside some baseballs and golf balls obeys Hooke's law over a wide range of elongation of the band. A segment of this material has an unstretched length / = 1.50 m and a mass m = 5.5 g. When a force F = 26 N is applied, the band stretches an additional length A/ = 0.29 m. (a) What is the speed of transverse waves on this stretched rubber band? (b) Find the time required for a transverse pulse to travel the length of the rubber band. (a) Number i IM (b) Number i Units Units <

A string oscillates according to the equation y' = (0.752 cm) sin[(7/5.0 cm-1)x] cos[(29.6 t s )t]. What are the (a) amplitude and (b) speed of the two waves (identical except for direction of travel) whose superposition gives this oscillation? (c) What is the distance between nodes?

Earthquakes at fault lines in Earth's crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves). The P-waves have a speed of about 6 km/s. Estimate the average bulk modulus of Earth's crust given that the density of rock is about 2,800 kg/m3.

The drawing shows a frictionless incline and pulley. The two blocks are connected by a wire (mass per unit length = 0.0224 kg/m) and remain stationary. A transverse wave on the wire has a speed of 88.1 m/s. Neglecting the weight of the wire relative to the tension in the wire, find the masses (a) m, and (b) m2 of the blocks. m2 " 1 30.0° (a) Number Units kg (b) Number i Units kg

A string that is stretched between fixed supports separated by 51.4 cm has resonant frequencies of 792.0 and 594.0 Hz, with no intermediate resonant frequencies. What are (a) the lowest resonant frequency and (b) the wave speed?

A 230 cm length of string has a mass of 3.7 g. It is stretched with a tension of 5.2 N between fixed supports. (a) What is the wave speed for this string? (b) What is the lowest resonant frequency of this string? (a) Number i (b) Number i Units Units <

Workers attach a 28.0 kg mass to one end of a 27.0 m long cable and secure the other end to the top of a stationary crane, suspending the mass in midair. If the cable has a mass of 24.0 kg, determine the speed of transverse waves at the middle and the bottom end of the cable. (Hint: Don't neglect the cable's mass. Because of it, the tension increases from a minimum value at the bottom of the cable to a maximum value at the top. The acceleration of gravity is g = 9.80 m/s².) HINT (a) speed (in m/s) at the middle of the cable m/s (b) speed (in m/s) at the bottom of the cable m/s
