An elastic band is hung on a hook and a mass is hung on the lower end of the band. when the mass is pulled downward and then released, it vibrates vertically. the equation of motion is
s = 8 cos t + 9 sin t, t ≥ 0,
where s is measured in centimeters and t in seconds. (take the positive direction to be downward.)

1) how far from its equilibrium position does the mass travel? (round your answer to two decimal places.)
