Four students measure the mass of an object, each using a different scale. They record
their results as follows:
Student A B C D
Mass (g ) 49.06 49 50 49.2
Which student used the least precise scale? - (answer)C

The length and width of a rectangle are 1.125 m and 0.606 m, respectively. Multiplying,
your calculator gives
the product as 0.68175. Rounding properly to the correct number of significant figures,
the area should be written as - (answer)0.682 m2

Suppose that an object travels from one point in space to another. Make a comparison
between the displacement
and the distance traveled - (answer)The displacement is either less than or equal to the
distance traveled

approaches a traffic light. Make
a statement concerning its acceleration. - (answer)The car is decelerating, and its
acceleration is negative.
Suppose a can, after an initial kick, moves up along a smooth hill of ice (no friction).
Make a statement
concerning its acceleration - (answer)It will have the same acceleration, both up the hill
and down the hill.
Suppose a ball is thrown straight up. Make a statement about the velocity and the
acceleration when the ball
reaches the highest point. - (answer)Its velocity is zero and its acceleration is not zero.
Ball A is dropped from the top of a building. One second later, ball B is dropped from the
same building. As
, time progresses, the distance between them - (answer)increases
Ball A is thrown downward from the top of a building. One second later, ball B is thrown
upward from the
same at the same speed. Which one has the greatest average speed during the first
second of its flight? - (answer)A
Ball A is thrown downward from the top of a building. One second later, ball B is thrown
upward from the
same at the same speed. Which one has the greatest average acceleration during the
first second of its flight? - (answer)The two bricks accelerate at the same rate
Ball A is thrown downward from the top of a building. One second later, ball B is thrown
upward from the
same at the same speed. Which one has the greatest speed just before impact? -
(answer)Both A and B have the same speed
Suppose a skydiver jumps from a high-flying plane. What is her acceleration when she
reaches terminal
velocity? - (answer)It is essentially zero.
The area under a curve in a velocity versus time graph gives - (answer)displacement.
The slope of a velocity versus time graph gives - (answer)acceleration.

far do you travel during
this inattentive period? - (answer)80 m
A cart with an initial velocity of 5.0 m/s experiences a constant acceleration of 2.0 m/s2
in the same direction as
its motion. What is the cart's displacement during the first 6.0 s of its motion? -
(answer)66 m
A cart with an initial velocity of 5.0 m/s experiences a constant acceleration of 2.0 m/s2
opposite the direction
of its motion. What is the cart's displacement during the first 6.0 s of its motion? -
(answer)-6 m
A car starting from rest moves with constant acceleration of 2.0 m/s2 for 10 s, then
travels with constant speed
for another 10 s, and then finally slows to a stop with constant acceleration of -2.0 m/s2.
How far does it travel? - (answer)400 m
A car goes from 40 m/s to 80 m/s in a distance of 200 m. What is its average
acceleration? - (answer)12 m/s2
