a cyclist named carly daugherty accelerates from 0 m/s to 8 m/s in 3 seconds. what is her acceleration? is this acceleration higher than that of soul train’s car, which accelerates from 0 to 30 m/s in 8 seconds? how do you know

           Magnitude of acceleration =

                                     (change in speed) / (time for the change) .

Magnitude of Carly's acceleration =

                                                     (8 m/s) / (3 sec)  =  2-2/3 m/s²

Magnitude of Soul Train's acceleration =

                                                    (30 m/s) / (8 sec) = 3.75 m/s² .

Soul Train's acceleration is about 41% greater than Carly's.
