Question

A transverse wave on a string is given by the formula D(x,t)=0.11sin(3.3x?18.0t), where D and x are in m and t is in s.

a) At t=0.17s, what is the transverse displacement of the point on the string where x=0.54m? Important hint: Does it matter whether your calculator is set to degrees or radians (deg or rad) for this problem? If yes, which setting should you use? Express your answer using two significant figures.

D(0.54m,0.17s) =

b) At t=0.17s, what is the (transverse) velocity of the point on the string where x=0.54m? Indicate the direction of velocity with the sign of your answer. Express your answer using two significant figures.

?D/?t(0.54m,0.17s) =

c) At t=0.17s, what is the (transverse) acceleration of the point on the string where x=0.54m? Indicate the direction of acceleration with the sign of your answer.

Express your answer using two significant figures.

?^2D/?^2t(0.54m,0.17s) =
