Answer:

6.64 m/s²

Explanation:

Given in the question,

time it take to accelerate the motorcycle = 4.22 seconds

final speed motorcycle reach = 28 m/s

initial speed of motorcycle = 0 m/s

Formula to calculate

average acceleration = Δv / Δt

                                    = finalspeed - initialspeed / 4.22

                                    = 28 - 0 / 4.22

                                    = 28/4.22

                                    = 6.64 m/s²
