A runner makes one lap around a 200 m track in 25 seconds. What were the runner's average speed and average velocity? An object from rest with a constant acceleration of 8 m/s2 along a straight line. Find the: a. final velocity; b. ave. velocity in 5 seconds; and c. distance in 5 seconds. An object moving at 13 m/s slows down uniformly at a rate of 2 m/s each second for a time of 6 seconds. Find the: a. final velocity; b. ave. velocity in 6 seconds; and c. distance in 6 seconds.
