If the spring's initial position is 0.098 meters from the origin, and the spring is continually displaced to a position of 0.299 meters from the
origin (Wall) with the required applied Force of 84.5 Newtons by the
block, causing it to accelerate constantly at 7.399 meters per second
squared, what is the spring constant k? ROUND answers to 1 decimal
place, NO UNITS!!!

1/0.14nm = 10^10/1.4 a lot

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

your answer is, orbit around the nucleus
