1) A speeding motorist traveling 30 m/s passes a stationary police officer. The officer immediately begins pursuit at a constant acceleration of 3 m/s2 . a) How much time will it take for the police officer to reach the speeder? b) What is the velocity of officer when he catches the speeder? c) Plot two graphs, show the displacement vs. time for both motorist and police in one graph and velocity vs. time for both of them in a the other graph.

  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.
