You and your dog go for a walk to the park. On the way, your dog takes may side trips to chase
squirrels. When you arrive at the park, do you and your dog have the same displacement? -
ANSYes
Does the displacement of an object depend on the specific location of the origin of the
coordinate system? - ANSNo
If the position of a car is zero, does its speed have to be zero? - ANSNo
Does the odometer in a car measure distance or displacement? - ANSDistance
Does the speedometer in a car measure velocity or speed? - ANSSpeed
You drive for 30 minutes at 30 mi/h and then for another 30 minutes at 50 mi/h. What is your
average speed for the whole trip? - ANSEqual to 40 mi/h
You drive 4 miles at 30 mi/h and then another 4 miles at 50 mi/h. What is your average speed
for the whole 8-mile trip? - ANSLess than 40 mi/h
If the average velocity is non-zero over some time interval, does this mean that the
instantaneous velocity is never zero during the same interval? - ANSNo
If the velocity of a car is non-zero, can the acceleration of the car be zero? - ANSYes
When throwing a ball straight up, which of the following is true about its velocity v and
acceleration a at the highest point in its path? - ANSv is zero but a is non-zero
You throw a ball straight up into the air. After it leaves your hand, at what point in its flight does it
have the maximum value of acceleration? - ANSIts acceleration is constant everywhere
You throw a ball upward with an initial speed of 10 m/s. Assuming that there is no air resistance,
what is its speed when it returns to you? - ANS10 m/s
Alice and Bill are at the top of a cliff of height H. Both throw a ball with initial speed of v. Alice
throws straight down and Bill straight up. The speeds of he balls when the hit the ground are VA
and VB. If there is no air resistance, which is true? - ANSVA = VB
, The acceleration is always the slope of the velocity versus time graph and the velocity is always
the slope of the position versus time graph. - ANSTrue
If the velocity versus time graph is a horizontal line, then that object cannot be accelerating. -
ANSTrue
Suppose that an object is moving with constant non-zero acceleration. Which of the following is
an accurate statement concerning its motion? - ANSIn equal times its velocity changes by equal
amounts
How many significant digits are in 0.000054? - ANStwo
How many significant digits are in 3.001 x 105 ? - ANSfour
The first several digits of Π are known to be 3.14159265358979. What is this number rounded
to five significant digits? - ANS3.1415
What is 150 miles per hour converted to meters per second? 1 miles = 1600 m. The answer is
closest to: - ANS67 m/s
A standard letter page is 8.5 in by 11.0 in. What is its area in cm2? 1 in = 2.54 cm - ANS600
cm^2
A warehouse is 20.0 yards long, 10.0 yards wide, and 15.0 ft high. What is its volume in SI
units? 1 yard = 3 ft and 1 m = 3.281 ft. - ANS1200 m^2
A driver is driving his car at 30 m/s. Suddenly, he pushes on the brakes to stop with the constant
acceleration of 10 m/s^2. How far does the car travel before it comes to a full stop? - ANS45 m
A driver is driving his car at 30 m/s. Suddenly, he pushes on the brakes to stop with the constant
acceleration of 10 m/s^2. How long does it take for the car to come to a full stop? - ANS3
seconds
A ball is thrown straight up vertically. The ball reaches to the height of 100 m. g=9.8 m/s^2 -
ANS
What is the initial speed of the ball when it was thrown up? - ANS44.3 m/s
A ball is thrown straight up vertically. The ball reaches to the height of 100 m. g=9.8 m/s^2 -
ANS
How long does it take for the ball to reach the maximum height? - ANS4.5 seconds
