If a ball with an original velocity of zero is dropped from a tall structure and it takes 7 seconds to hit the ground, what velocity does the ball have when it reaches the ground? a. 34.3 m/s b. 68.6 m/s c. 156.8 m/s d. 240.1 m/s

  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.
