Question

2.
A wave travelling along a string is represented by
at
y = 2.5 sin (0·002 x + 91 +5)
where x and y are in cm. t in second.
Find (i) displacement of a particle
x = 1.5 cm and t = 0.5 s, (ii) speed of a particle at
x=1.5 cm and t = 0.5 s. Is this speed of the particle
equal to the speed of propagation of the wave.
[Ans. - 0-77 cm, 6.95 cm -1 ; No]​

Answer 1

Answer:

[answer is 77cm , 6.95cm -1; no]
