Aball is dropped and falls with an acceleration of 9.8 m/s^2 downward. it hits the ground with a velocity of 49 m/s downward. how long did it take the ball to fall to the ground

more than, less

less than, more

  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.
