a driver notices a upcoming speed limit change from 20m/s to 11m/s. if she estimates the speed limit will change in 50 m, what acceleration is needed to reach the new speed limit before it begins?

temp rises, and expansion

it doesn't. it was imagined up in the middle ages.

  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.
