Background Info:
--------------------------
Consider a block of mass m attached to a spring with force constant k, as shown in the figure http://session.masteringphysics.com/problemAsset/1003614/20/168450A.jpg . The spring can be either stretched or compressed. The block slides on a frictionless horizontal surface, as shown. When the spring is relaxed, the block is located at x=0. If the block is pulled to the right a distance A and then released, A will be the amplitude of the resulting oscillations.
Assume that the mechanical energy of the block-spring system remains unchanged in the subsequent motion of the block.
--------------------------
The following questions refer to the figure http://session.masteringphysics.com/problemAsset/1003614/20/168450B.jpg that graphically depicts the oscillations of the block on the spring.
Note that the vertical axis represents the x coordinate of the oscillating object, and the horizontal axis represents time.
----------------------
Which points on the x axis are located a distance A from the equilibrium position?
A: R only
B: Q only
C: both R and Q
---------------------
Suppose that the period is T. Which of the following points on the t axis are separated by the time interval T?
A: K and L
B: K and M
C: K and P
D: L and N
E: M and P
------------------------------
Now assume that the x coordinate of point R is 0.12 m and the t coordinate of point K is 0.0050 s.
What is the period T ?
-------------------------------------
How much time t does the block take to travel from the point of maximum displacement to the opposite point of maximum displacement?
--------------------------------
What distance d does the object cover during one period of oscillation?
-----------------------------------
What distance d does the object cover between the moments labeled K and N on the graph?
--------------------------
Please state the correct answer from setup of formulas to final answer and explain your answers reasoning clearly
