Acceleration Practice
1.
A ball is thrown down at 10 m/s from a height of 30m.
a. What is the final velocity when it hits the ground?
b. How long does it take to hit the ground?
2.
A ball
hits
the
ground
going
80m/s.
It
was
thrown
from
a height
of
10m.
What
was
the
initial
velocity of the ball?
3.
A ball is dropped from the eifel tower (308m). How long does it take to hit the ground?
4. A person drops a rock into a well and it hits the bottom of the well 2.4 seconds later.
a. How deep is the well?
b. How fast was the rock going when it hit the bottom of the well?
5.
A person throws a wrench up in the air and catches it 1.8 seconds later.
a. How high did the wrench go?
b. How fast was the wrench going when it left their hand?
6. A person throws a rock directly up into the air with a velocity of 22.4m/s.
a.
How high
is
the
rock
2.0
seconds
into
its
flight?
b. How high is the rock 4.0 seconds into its flight?
7. A car drives toward the North at a velocity of 20m/s for 180 seconds. It then drives South for
300 seconds with a velocity of 20m/s.
a. What is the total distance traveled by the car?
b. What is the displacement of the car?
c. What is the average velocity of the car?
d. What is the average speed of the car?
8. A car on the freeway is traveling 22m/s when it begins to accelerate. It accelerates uniformly for
a distance of 400m. At the end of 400m, the driver looks at their speed and they are now
traveling at
30m/s.
a. What was the acceleration of the car during the 400m?
b. How long did it take for the car to travel the 400m?
Graph and answer the questions
9. A car accelerates from rest at a rate of +5.0m/s2 for 4.0 seconds. Then it accelerates at a rate of
10m/s2 for 2.0 seconds. It then stops accelerating and remains at a constant speed for 5.0
seconds. It then accelerates at a rate of ‐7.5m/s2 for 2.0 seconds. Then it accelerates at ‐1.0
m/s2 until it stops.
a. What is the average velocity of the car?
b.
What is the total distance traveled?
c. What is the displacement of the car?
