ASK YOUR 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 1 (cos(8t) - 6 sin(8t)) where y is the displacement (in meters) and t is the time (in seconds). Equilibrium WWW 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.)
