Intro to Physics Quiz
Make sure to read the direction carefully and try not to leave any questions blank. Make sure to show ALL your
work.
Directions: Each problem is looking for you to solve for either displacement, velocity, or acceleration. Include
correct units or you will lose half a point.
1. An object moves 12 meters north and then 5 meters east.
(a) Calculate the displacement of the object.
2. The pitcher’s mound is 7 m from home plate. The pitcher then throws the ball to the outfielder who is 28
meters away from the pitcher.
(a) What is the total displacement?
(b) The ball takes 7 seconds to travel from the pitcher’s mound to the outfielder. What is its velocity?
(c) When the pitcher first throws the ball, it is moving at a velocity of 2 m/s. However, by the time it
reaches the outfielder, it is at a velocity of 37 m/s. It still takes 7 seconds. What is the acceleration?
Use the figure to answer questions 3-6.
s
p
C
t
q
x
B
A
D
v
r
u
w
3. Find the average velocity of:
A = ______________.
B = ______________.
C = ______________.
D = _____________.
4. What is the acceleration between point p and r.
5. What is the acceleration between point s and u.
Directions: Draw the correct force diagrams for each problem.
.
11. Find the acceleration of each of the situations below. Then rank them 1-6. 1 is the fastest and 6 is the slowest.
In some cases, there is only one arrow, that means there is only one force. For example, in one there is 9 N
to the right. That means you shouldn’t assume any other forces.
