If the velocity of the object changes from 2 cm / sec to 11 cm / sec in 10 seconds, then at what average rate is the velocity changing?
It requires 8.2 seconds, starting from rest, for a ball to roll the 75 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 13 seconds to cover a distance of 163 meters.
