50 points 2. The graph shows the vertical displacement y, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds, x.

(a) What is the weight’s maximum displacement?

(b) From its resting position, how long does it take the weight to bounce one

direction, then the other, and then return to its resting position?

(c) What is the graph’s frequency and what does it indicate in this situation?

(d) How is the weight moving during the time period x = 6 to x = 7.5?
