Question: 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?

Question:The metric prefix for one one-thousandth is
Answer: milli


Question:The number of significant figures in 10001 is
Answer: 5


Question: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

Question: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


Question:Suppose that a car traveling to the East (+x direction) begins to slow
down as it approaches a traffic light. Make
a statement concerning its acceleration.
Answer: The car is decelerating, and its acceleration is negative.


Question: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.


Question: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.

Question: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


Question: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


Question: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


Question:Suppose a skydiver jumps from a high-flying plane. What is her
acceleration when she reaches terminal
velocity?
Answer: It is essentially zero.
