from 85 m/s to 45m/s in a period of 4.5 sec. What is the acceleration of the
                                 dragster?


•   G = Vf Vi T                             U=A

3.The table below shows data for a ball rolling downhill. Fill in the missing
       data and then determine the acceleration of the rolling ball.


          Time (seconds)                            Speed (km/hr)
                 0                                        0

                10                                        15


   Every 2 seconds the ball goes 3km/hr faster


    Every 1 second it goes 1.5 km/hr faster


      Acceleration is 1.5 km/hr/sec
