Homework Statement
The displacement of a pulse traveling on a horizontal string is approximated by:
y(x,t) = 0.05/((1.5x - 3t)^2)+1
where x and y are measured by metres.
i) the velocity of propigation
ii) the direction of motion
iii) the maximum displacement
iv) the displacement at x = 4m after t = 2.5
v)the particle velocity (magnitude and direction) at x = 4 after 2.5s
Homework Equations
Unsure
The Attempt at a Solution
My problem is slightly in understanding the question.
i) Well I think the velocity is given by the change in x over the change in t. Is that what is being asked? I am not sure.
ii) I think that the wave is going in the positive direction due to the negative in (1.5x - 3t) since I read that in the notes but that was using an equation that wasnt squared or having a value on top of it.
iii) Will the just be 0.05/1 so when x and t = 0.
iv) For this part I think I am just plugging those values into the equation right?
v) I am very unsure about this part.
Help with any parts would be appriciated!
