Originally Answered: A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. What is the acceleration of the car? Its average speed is 110 m/5.21 sec, so its speed at the end is 220 m/5.21 sec. Its acceleration is (220 m/5.21 sec)/5.21 sec = 8.105 m/sec^2.
