The springs shown in the figure (12-E7) are all upstretched in the beginning when a man starts pulling the block. The can exerts a constant force F on the block. Find the amplitude and the frequency of the motion of the block.

Since are in series, let an equivalent spring constant be Therefore

, so equivalent spring constant k is given as
