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?

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.

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.
