Question
A 45.0-N force stretches a vertical spring0.250 m.(a) What mass must be suspended form the spring so thatthe system will oscillate with a period of 2.50 s?
(b) If the amplitude of the motion is 0.050 m and the period isthat specified in part (a) where is the object and in whatdirection is it moving 0.35 s after it has passed the equilibriumposition, moving downward? Take the positive direction to beupward.
(c) What force (magnitude and direction) does the spring exert onthe object when it is 0.010 m below theequilibrium position, moving upward?
