Calculate the acceleration of Josh riding his bicycle in a straight line that speeds up from 4 m/s to 6 m/s in 5 seconds. Initial Speed . Final Speed . Time . Acceleration =

Initial Speed 4m/s. Final Speed 6m/s. Time 5 seconds . Acceleration =0.4m/s²

Explanation:

The acceleration is the rate of change of velocity during time t .

acceleration = Final velocity- Initial velocity/ Time

                    = Vf- Vi/ t

            a = Δv/ Δt

                   = 6m/s- 4m/s/ 5s

                   = 2m/s/ 5s

                  = 0.4m/s²

It can also be defined as the difference of the initial and final velocity ( velocities measured in meters per second) during the given time t measured in seconds .The SI unit of acceleration is meter per second squared.

If the velocities are not measured in meters per second or time is not measured in seconds then the units are changed accordingly.
