A scooter begins at rest at t0 = 0 seconds. The scooter then accelerates and covers a distance d = 526 m, in a time tf = 105 s. The scooter's motion is in the Northern direction.
What is the scooters average speed during this period in m/s?
What is the scooters displacement in the northen direction during the period in meters?
Whats is the scooters average velocity in the northen direction in this period in m/s?
if the scooters velocity was 27 m/s, what was the scooters average acceleration in the northen direction in this period in m/s2?
