Chapter 3 Acceleration
  Here is your chance to apply what you've learned in this chapter.

Acceleration is defined as change in velocity per unit time. You should be able to calculate average velocity. You should be familiar with velocity-time graphs. Acceleration, velocity and displacement are closely related to each other. You should be able to manipulate them to solve problems.

You can use the formula sheet if you need help.

Chapter 3 Quiz:

1. How long does it take for a car to change its velocity from 10 m/s to 25 m/s if the acceleration is 5 m/s2?

s

2. A rat and a cat is 35 m apart. When the rat started to run at 2 km/h (0.556 m/s), the cat started to chase him at 1 m/s2. Can the cat catch the rat in 10 seconds?

(yes/no)

3. A car has a constant acceleration of 4 m/s2, starting from rest.

a. How fast is it traveling after 5 seconds? m/s

b. How far is it traveling after 5 seconds? m

c. How far has it traveled by the time it reached the speed of 40 m/s? m

4. A car is at velocity of 20 km/h. If the car traveled 120 km in 3 hours at constant acceleration, what is its final velocity?

km/h

5. A car travels at constant acceleration of 5 m/s2 from rest. How far has it traveled by the time it reached the velocity of 72 km/h (20 m/s)?

m

6. How long will it take for a falling object to reach 108 m/s if its initial velocity is 10 m/s?

s

7. What is the final velocity of an apple if it falls from a 100m-tree?
