An object is attached to a coiled spring. It is pulled down a distance of 4 units from its equilibrium position, and then released. The time for one complete oscillation is 3 seconds. a. Give an equation that models the position of the object at time t. s(t) = (Simplify your answer. Type an exact answer, using x as needed. Use integers or fractions for any numbers in the expression.) b. Determine the position at time t= 1.94 sec. units (Round to the nearest hundredth as needed.) c. Find the frequency. oscillation per sec (Use integers or fractions for any numbers in the expression.)
