19. [-/1 Points] A weight is oscillating on the end of a spring (see figure). The displacement from equilibrium of the weight relative to the point of equilibrium is given by y = = 12 (cos(8t) - 2 sin(8t)) where y is the displacement (in meters) and t is the time (in seconds). WW Equilibrium Find the times when the weight is at the point of equilibrium (y = 0) for 0 s t s 1. (Enter your answers as a comma-separated list. Round your answers to two decimal places.) = Need Help? Read It Watch It
