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?
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?
3. A car has a constant
acceleration of 4 m/s2, starting from
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?
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)?
6. How long will it take for a
falling object to reach 108 m/s if its initial
velocity is 10 m/s?
7. What is the final velocity of an
apple if it falls from a 100m-tree?
