Solutions.
A ball is released from rest from the twentieth floor of a building. After 1 s, the ball has fallen
one floor such that it is directly outside the nineteenth-floor window. The floors are evenly
spaced. Assume air resistance is negligible. What is the number of floors the ball would fall in 3s
after it is released from the twentieth floor? - Answer 7 to 10 floors
A student is provided with a battery-powered toy car that the manufacturer claims will always
operate at a constant speed. The student must design an experiment in order to test the validity
of the claim. Which of the following measuring tools can the student use to test the validity of
the claim? - Answer Photogates placed at the beginning, end, and at various locations along
the track that the car travels on ans
A meterstick to measure the distance of the track that the car travels on
Two students want to determine the speed at which a ball is released when thrown vertically
upward into the air. One student throws the ball into the air while the other student measures
the total time that the ball is in the air. The students use a meterstick to measure the release
height of the ball. Which of the following equations should the students use to determine the
speed at which the ball was released? - Answer Use y=y0+vy0t+12ayt2y=y0+vy0t+12ayt2 from
the moment in time in which the ball was released to the moment in time in which the ball hits
the ground.
A car initially at rest accelerates at 10m/s^2. The car's speed after it has traveled 25 meters is
most nearly - Answer 22.0 m/s
A student wants to study the motion of an object that has a constant acceleration. Which of the
following experiments could the student conduct to provide the best situations in which an
object has a constant acceleration? Select two answers. - Answer Release a ball from rest near
Earth's surface. Release a cart from rest such that it travels down an incline of 40° with respect
to the ground.
A ball is moved from Earth to a planet that has a gravitational acceleration that is double that of
Earth. How does the gravitational force on the ball when it is on the new planet compare to the
gravitational force on the ball when it is on Earth? - Answer The gravitational force on the ball
when it is on the new planet is double the force on the ball when it is on Earth.
, acceleration values and determines that the cart's mass is 0.4kg. When placed on a balance, the
cart's mass is found to be 0.5kg. Which of the following could explain the difference in mass? -
Answer The track was not level and was tilted slightly downward.
An object travels down a ramp at a constant acceleration. The object experiences a force of
friction and a gravitational force. Which of the following could be true about the motion of the
object? - Answer The force of friction between the surface and the object is less than the
component of the gravitational force that is parallel to the ramp.
A ball of mass m is found to have a weight Wx on Planet X. Which of the following is a correct
expression for the gravitational field strength of Planet X? - Answer The gravitational field
strength of Planet XX is Wx/m.
A student must determine the relationship between the inertial mass of an object, the net force
exerted on the object, and the object's acceleration. The student uses the following procedure.
The object is known to have an inertial mass of 1.0kg.
Step 1: Place the object on a horizontal surface such that frictional forces can be considered to
be negligible.
Step 2: Attach a force probe to the object.
Step 3: Hang a motion detector above the object so that the front of the motion detector is
pointed toward the object and is perpendicular to the direction that the object can travel along
the surface.
Step 4: Use the force probe to pull the object across the horizontal surface with a constant force
as the force probe measures force exerted on the object. At the same time, use the motion
detector to record the velocity of the object as a function of time.
Step 5: Repeat the experiment so that the object is pulled with a - Answer No, because the
motion detector should be oriented so that the object moves parallel to the line along which
the front of the motion detector is aimed.
A book is at rest on the top of a table. A student makes the following claim: "An attractive
electromagnetic force is exerted on the book from the table, and this force can also be classified
as the normal force." Which of the following statements correctly justifies the student's claim? -
Answer The claim is incorrect because the charged particles of the table exert an upward
repulsive force on the charged particles of the book.
A student must design an experiment to determine the relationship between the mass of an
object and the resulting acceleration when the object is under the influence of a net force.
Which of the following experiments should the student conduct in order to determine the
