A 2.00-kg block is attached to the end of a horizontal ideal spring and rests on a frictionless surface. The other end of the spring is attached to a wall. After being displaced a small distance and released from rest, the block is observed to oscillate at a frequency of 2.77 Hz. The spring is then cut in half. One of the halves is then connected between the wall and the block.
What will be the frequency when the block is displaced and released from rest again?
