- Harmonic Motion The displacement from equilibrium of an oscillating weight suspended by a spring is given by y(t)=12cos6t where y is the displacement in feet and t is the time in seconds. Find the displacement when (a) t = 0, (b) t=14, and (c) t=12.arrow_forwardOcean Tide The tide, or depth of the ocean near the shore, changes throughout the day. The water depth d (in feet) of a bay can be modeled by d=3528cos6.2t where t represents the time in hours, with t=0 corresponding to 12:00 a.m. (a) Algebraically find the times at which the high and low tides occur. (b) If possible, algebraically find the time (s) at which the water depth is 3.5 feet. (c) Use a graphing utility to verify your results from parts (a) and (b).arrow_forwardOscillating Spring A mass attached to a spring oscillates upward and downward. The displacement of the mass from its equilibrium position after t seconds is given by the function d(t)=3.5cos(2t), where d is measured in centimeters (Figure 12). Find all times at which the displacement is zero.arrow_forward
