1. Agra runs around a circular track of radius 70 m. It takes him 140 s to complete a revolution of the track. If he runs at constant speed, calculate:
a. his speed,
b. his average velocity between points A and B,
c. his average speed during a revolution.
d. his average velocity during a revolution.
2. What is the final velocity of an apple if it falls from a 100m-tree?
3. If a car has a constant acceleration of 4 m/s2, starting from rest, how fast is it traveling after 5 seconds?
4. If a car has a constant acceleration of 4 m/s2, starting from rest, how far has it traveled by the time it reaches the speed of 40 m/s?
5. Aurelia is driving through town at 25.0 m/s and begins to accelerate at a constant rate of -1.0 m/s2. Eventually Aurelia comes to a complete stop. calculate the distance that Aurelia travels while decelerating.
