The figure below shows the position of a car every 10 seconds. The red arrows "represents" the average velocities between the two dots, i.e., the arrow between 20 s and 30 s "represents" the average velocity between 20 s and 30 s. This, in turn, gives an estimate of the velocity at 25 sec, halfway between the two times. Which arrows best "represents" the average acceleration between 5 sec and 15 sec? This gives an estimate of the acceleration at 10 sec. [ Select ] Which arrows best "represents" the average acceleration between 35 sec and 45 sec? This gives an estimate of the acceleration at 40 sec. [ Select ]
