Hi, so I have this question:
A wave pulse on a string has the dimensions shown in the figure (Figure 1) at t = 0. The wave speed is 40 cm/s.
a) Draw the total wave on the string at t=15ms, 20ms 25ms, 30ms, 35ms, 40ms and 45ms. b) repeat part (a) for the case in which the end of the string is free to slide along a pole.
I can do part a for 15ms and 20ms but not sure about the rest.http://oi55.tinypic.com/25khmc0.jpg
I get that i need to for example:
400mm/s * 25*10^-3 = 10
so the graph moves towards the left by 10mm but the end point can only move 8mm before it reaches the fixed point so how would i draw it?
Also how would i do part b?
The graph is show belowhttps://s.yimg.com/hd/answers/i/1050e382d8554e5b838204097000f963_A.png?a=answers&mr=0&x=1447003459&s=affee6d379f3c547fcb47aaf2aab461b Thanx:)
