Ill Filladelphia on March 21 alld Ivay 69. The motion of a spring that is subject to a frictional force or a damping force (such as a shock absorber in a car) is often modeled by the product of an exponential function and a sine or cosine function. Suppose the equation of motion of a point on such a spring is s(t) = 2e-15t sin 2 art where s is measured in centimeters and t in seconds. Find the velocity after t seconds and graph both the position and veloc- ity functions for 0
