Question:

Consider the glider of Example 7.7 (Section 7.2) and Fig. 7.16.
(a) As in the example, the glider is released from rest with the spring stretched 0.100 m. What is the speed of the glider when it returns to x = O?
(b) What must the initial displacement of the glider be if its maximum speed in the subsequent motion is to be 2.50m/s?
