Question

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

What is the weight's maximum displacement?
My answer: 28

From it's resting position, how long does it take the weight to bounce one direction, then the other, and then return to it's resting position?
My answer: It takes 3 seconds to make a complete cycle.

What is the graph's frequency and what does it indicate in this situation?

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

Answer 1

Someone please help my friend ^.^ thank you.

Answer 2

I'm not sure about the 3rd one, but I think the 4th one is where the weight is bouncing up from it's resting position and then falling back down to it's restion postion (then after the 7.5 seconds it would keep going until it can't then going back up to its resting place, etc.)
