If the velocity of the object changes from 4 cm / sec to 16 cm / sec in 6 seconds, then at what average rate is the velocity changing?
Starting from rest, a ball rolls down a constant incline. It requires 7.1 seconds to roll the 30 centimeter length of the incline.
An object which accelerates uniformly from rest will attain a final velocity which is double its average velocity.
