If the velocity of the object changes from 5 cm / sec to 14 cm / sec in 3 seconds, then at what average rate is the velocity changing?
It requires 9.7 seconds, starting from rest, for a ball to roll the 99 centimeter length of a uniform incline.
An object which accelerates uniformly from rest will attain a final velocity which is double its average velocity.
At what average rate does the velocity of an airplane change, if it accelerates uniformly down a runway, starting from rest, requiring 12 seconds to cover a distance of 164 meters.
