Homework Help: Physics

Posted by Vladimir on Friday, July 13, 2012 at 10:53am.

Suppose the slope of a beach underneath the ocean is 20 cm of dropoff for every 1.6 m of horizontal distance. A wave is moving inland, slowing down as it enters shallower water. What is its acceleration when it is 12 m from the shoreline? (Let the +x direction be towards the shoreline. Indicate the direction with the sign of your answer.)

The answer is supposed to be -0.613m/s^2. I'm stumped on how to get this answer. I figured out that the total distance downward the beach goes at 12 m to be 1.5 m. However, I'm not sure if that's useful or not. Any help is appreciated.
