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 should have a sheet
of paper and a pencil with you.

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/s^{2}?

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/s^{2}.
Can the cat catch the rat in 10 seconds?

(yes/no)

3. A car has a constant
acceleration of 4 m/s^{2}, 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/s^{2} 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?
