3. An athlete walks with a piece at ticker tape attached to herself with a tape timer running, and produces the tape shown. According to the tape, she was traveling with
a)
Constant velocity
b)
Positive acceleration
c)
Negative acceleration
d)
Constant velocity, then negative acceleration
4.
A track coach with a meter stick and a stopwatch is trying to determine if a student is walking with a constant speed. He should
a)
Measure the walker’s speed repeatedly for short time intervals to see if it is always the same.
b)
Measure the total distance the students travels and the total time to get the average speed.
c)
Measure the beginning and ending speed only to see if they are the same.
d)
Use the meter stick to measure the student stride length and time how long it takes to take one step
5.
If a cart is traveling with uniform negative acceleration, what conclusion can be drawn about the forces acting on the cart?
a)
The cart must be frictionless.
b)
The cart must be rolling downhill.
c)
The cart must have a net unbalanced forces acting on it.
d)
No forces are needed; the cart will naturally slow down.
6.
A student wants to set up an experiment to determine the effect of a net force on an object’s acceleration. To do this, she should
a)
Vary the force acting on the object and the mass of the object at the same time
b)
Vary the mass of the object , but not the force acting on the object
c)
Vary the force acting on the object, but not the object mass
d)
Keep both the force acting on the mass and the mass of the object constant as it rolls along a horizontal surface
7.
A 2-kg block is dropped from the roof of a tall building at the same time a 6-kg ball is thrown horizontally from the same height. Which statement best describes the motion of the block and the motion of the ball?
a)
The 2-kg block hits the ground first because it has no horizontal velocity.
b)
The 6-kg ball hits the ground first because it has more mass.
c)
The 6-kg ball hits the ground first because it is round.
d)
The block and the ball hits the ground at the same time because they have the same vertical acceleration.
8.
A pitching machine launches a baseball horizontally with no spin. Which of the following statement correctly describes the ball’s motion in the air as the launch speed is increased?
a)
The ball’s acceleration increases, and the distance it falls in one second decreases.
b)
The ball’s acceleration remains the same, and the distances the ball falls in one second decreases
c)
The ball’s acceleration remains the same, and the distance it falls in one second increases
d)
The ball’s acceleration remains the same, and the distance it falls in one second remains the same
9.
A student is holding a book that has a weight of 20 N in his hands while sitting in a chair. The man claims that the book must be attracting Earth with a force of 20 N. His claim must be
a)
True due to newton’s third law of action reaction.
b)
False because Earth is much larger than the book.
10.
Which diagram of 5-kg mass resting on a table correctly represent the FORCE of the table on the mass?
a)
The 50kg pushing down shows the force of the table on the mass.
b)
The 5N pushing down
c)
The 50N pushing up from the center of the mass.
d)
The 5kg pushing up.
11.
Two students have a “tug-of-war” on a smooth gym floor. One student has a mass of 70-kg and is wearing socks, but no athletic shoes. The other student has a mass of 60-kg and is wearing athletic shoes. The student mostly to win will be
a)
The 60-kg student because he can pull harder on the 70-kg student
b)
The 70-kg student because he can pull harder on the 60-kg student
c)
The 60-kg student because he experiences a greater frictional force with the floor
d)
The 70-kg student because he experiences a greater frictional force with the floor
12.

a)
Only if the unicorn and the chair are at rest.
b)
Only if the unicorn and the chair are accelerating
c)
Only if the unicorn and the chair are moving with constant velocity
d)
in all of the above cases
13.
A dragon standing on a chair weighs 800N. In order for the chair to support the dragon, the chair must exert an upward force of
a)
less than 800N.
b)
800N.
c)
More than 800N.
d)
Cannot be determined.
14.
Automobile with front-wheel drive that have the engine located over the drive wheels that have better traction in snow than automobile with rear-wheel drive. This is most likely because
a)
The tire on the front-wheel drive automobile have a higher coefficient of friction than rear-wheel drive automobile.
b)
The front tires encounter the snow first.
c)
The front tires have a higher normal force than the rear-wheel tires because the engine is heavier than the rear of the automobile.
d)
The front wheels are used for steering
