Answer:
6.64 m/s²
Step-by-step 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
