Part A
Answer all questions in this part.
Directions (1–35): For each statement or question, choose the word or expression that, of those given, best
completes the statement or answers the question. Some questions may require the use of the 2006 Edition
Reference Tables for Physical Setting/Physics. Record your answers on your separate answer sheet.

1 Which pair of quantities represent scalar
quantities?
(1) displacement and velocity
(2) displacement and time
(3) energy and velocity
(4) energy and time
2 A sailboat on a lake sails 40. meters north and
then sails 40. meters due east. Compared to its
starting position, the new position of the sailboat
is
(1) 40. m due east (3) 57 m northeast
(2) 40. m due north (4) 80. m northeast
3 A ball is thrown straight upward from the surface
of Earth. Which statement best describes the
ball’s velocity and acceleration at the top of its
flight?
(1) Both velocity and acceleration are zero.
(2) Velocity is zero and acceleration is nonzero.
(3) Velocity is nonzero and acceleration is zero.
(4) Both velocity and acceleration are not zero.
4 As a student runs a plastic comb through her
hair, the comb acquires a negative electric
charge. This charge results from the transfer of
(1) protons from the comb to her hair
(2) protons from her hair to the comb
(3) electrons from the comb to her hair
(4) electrons from her hair to the comb
5 How would the mass and weight of an object on
the Moon compare to the mass and weight of the
same object on Earth?
(1) Mass and weight would both be less on the
Moon.
(2) Mass would be the same but its weight
would be less on the Moon.
(3) Mass would be less on the Moon and its
weight would be the same.
(4) Mass and weight would both be the same on
the Moon.
6 An object is moving with constant speed in a
circular path. The object’s centripetal
acceleration remains constant in
(1) magnitude, only
(2) direction, only
(3) both magnitude and direction
(4) neither magnitude nor direction
7 As shown in the diagram below, a rope attached
to a 500.-kilogram crate is used to exert a force of
45 newtons at an angle of 65 degrees above the
horizontal.
The horizontal component of the force acting
on the crate is
(1) 19 N (3) 210 N
(2) 41 N (4) 450 N
8 A spring with a spring constant of 68 newtons per
meter hangs from a ceiling. When a 12-newton
downward force is applied to the free end of the
spring, the spring stretches a total distance of
(1) 0.18 m (3) 5.7 m
(2) 0.59 m (4) 820 m
