15.55: a) and b) (1): The curve appears to be horizontal, and y v = 0. As the wave moves, the point will begin to move downward, and < y a 0. (2): As the wave moves in the + x -direction (to the right in Fig. (15.34)), the particle will move upward so y v > 0. The portion of the curve to the left of the point is steeper, so y a > 0. (3) The point is moving down, and will increase its speed as the wave moves; y v < 0, y a < 0. (4) The curve appears to be horizontal, and

Unformatted text preview: y v = 0. As the wave moves, the point will move away from the x-axis, and y a >0. (5) The point is moving downward, and will increase its speed as the wave moves; 0. 0, < < y y a v (6) The particle is moving upward, but the curve that represents the wave appears to have no curvature, so 0. and = y y a v c) The accelerations, which are related to the curvatures, will not change. The transverse velocities will all change sign....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
