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?
Starting from rest, a ball rolls down a constant incline. It requires 9.1 seconds to roll the 39 centimeter length of the incline.
An object which accelerates uniformly from rest will attain a final velocity which is double its average velocity.
In 11 seconds, a bicycle accelerating uniformly from rest covers a distance of 144 meters. At what average rate is its velocity changing?
