Chapter 10, Problem 10P

* The velocity of a vibrating object changes as a function of time as $v=-\left(0.6\text{m/s}\right)\cos \left[\left(2\pi {\text{s}}^{-1}\right)t\right]$. (a) Say everything you can about the motion. Draw a sketch of the situation when the motion starts (b) Represent the motion with a position-versus-time graph and a work-energy bar chart.
