Motion Daily Test 2nd Semester 2014-2015



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.
