Question

A vibrating string 53.0cm long is under a tension of 1.01N . The results from five successive stroboscopic pictures are shown in the figure (Figure 1) . The strobe rate is set at 5000 flashes per minute, and observations reveal that the maximum displacement occurred at flashes 1 and 5 with no other maxima in between.

How fast is point P moving when the string is in position 1?

(Answer must be in meters/second)

(***The frequence was found to correctly be 10.4Hz***)

Explanation / Answer

vy =w*1.5*sin kx sin wt

at max speed sin kx sin wt=1

hence

vy = 2*pi*f*1.5 =2*3.14*10.4*1.5 =0.98 m/s
