\fFind the derivative of: 7 (sin (9x7) ) 2.\fA mass on a spring bounces up and down in simple harmonic motion, modeled by the function s(t) = 9 cost where s is measured in centimeters and t is measured in seconds. Find the rate at which the spring is oscillating at t = 2 5. Round your answer to four decimal places. cm/s If an object is moving '1', and begins to accelerate T, then it.
