You are sitting at the beach, but you can't stop thinking about physics. You notice that the waves crash at the shore approximately every 3.6 seconds, and you estimate that at the moment one wave crashes the shore, the next one is roughly 4.3 m away. How fast would you say the waves are travelling towards the shore?

The mathematical description of any wave is given by 2T y(r, t) % 3D A sin (2 T ft Using the equation editor in the text box below, write the mathematical description of the particular wave shown in the figure below. Assume that y(0, 0) = 0. ) % (hint: find the parameters that describe this particular wave, and substitute them in the above expression.) y (cm) 24 m/s 4. 2 जमिन । -x (m) 20 4 8 12 -27 -4-
