Question: Solve the given problems by finding the appropriate derivative.
An object on the end of a spring is moving so that its displacement (in cm) from the equilibrium position is given by y = e-0.5t (0.4 cos 6t - 0.2 sin 6t). Find the expression for the velocity of the object. What is the velocity when t = 026 s ? The motion described by this equation is called damped harmonic motion.
