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 l = 1.50 m and a mass m = 5.6 g. When a force F = 17 N is applied, the band stretches an additional length Δl = 0.51 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.
t=l+delta l/ v
