Quiz: An amusement park game consists of throwing a quarter into a small
bowl. If you win, you get to take home a giant purple stuffed elephant. The dish
is on a shelf that is 0.4 m above the point where the quarter leaves your hand.
The horizontal distance between the bowl and the place where the quarter
leaves your hand is 1.8 m. Ignoring air drag, if you toss the quarter at an angle
of 60°, what initial velocity is needed to bring home the giant purple stuffed
elephant?
Ans: 4.8 m / s
Quiz: If the x-component of a vector is 3 and the y-component is 4, what
is the magnitude of the vector?
Ans: 5
Quiz: Which of the following is involved in uniform circular motion?
Ans: constant angular velocity

, Quiz: As shown, a crate of oranges and a crate of apples, each with a
different mass, are attached by a rope (with tension Toa). A second rope (To )
is attached to the crate of oranges, and the entire system is pulled with a
constant acceleration a by this rope. Which of the following is true of the
tensions?
Ans: Toa > To
Quiz: How can you calculate the magnitude of a vector using scalar
products?
Ans: Multiply it by itself and take the square root.
Quiz: Suppose you weigh an object and the reading you get from the scale
is 0.0070 kg. How many significant digits does your measurement have?
Ans: Two
Quiz: Consider two objects sliding down an incline without rolling. If the
objects don't have the same mass, the heavier object will accelerate at a faster
rate than the lighter one.

m/s2.
Ans: 606 m
Quiz: Which of the following statements concerning friction is incorrect?
Ans: The force of static friction ( fs ) between parallel surfaces in contact is
given by: fs = μsN.

suddenly slips out of his hand. How tall is the building if Superman has a
minimum time of 2.30 s to catch the woman before she hits the ground?
Ans: 25.9 m
Quiz: Kylie throws Kyra a kiwi. The kiwi leaves Kylie's hand at a height of
1.3 m from the ground and Kyra grabs it out of the air at a height of 1.6 m.
Kylie throws the kiwi at an angle of 33° relative to the horizontal. The kiwi is
in the air for 1.1 s. How far apart are Kylie and Kyra standing? (Assume there
is no drag force that no wind is blowing.)
Ans: 9.6 m
