If the velocity of the object changes from 2 cm / sec to 12 cm / sec in 4 seconds, then at what average rate is the velocity changing?
Starting from rest, a ball rolls down a constant incline. It requires 3.7 seconds to roll the 65 centimeter length of the incline.
An object which accelerates uniformly from rest will attain a final velocity which is double its average velocity.
In 12 seconds, a bicycle accelerating uniformly from rest covers a distance of 148 meters. At what average rate is its velocity changing?
