A 45.0-N force stretches a vertical spring0.250 m.
(a) What mass must be suspended form the spring so that the 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 the equilibrium position, moving upward?
A particle oscillates with S.H.M. The maximum displacement from its mean position is 0.5 meter and frequency of motion is 10 Hz. at time t=0, particle is located at 0.15 meter and has the velocity of 24.0 m/s towards the negative x-axis.
