### Question 1

Question
The Velocity versus Time graph above represents the motion of a toy car. Which of the following represents the Speed versus Time graph of the toy car?
• A
• B
• C
• D

### Question 2

Question
Activity 1 Question 1 The video indicates that there are 96 frames for each second. How many seconds do 48 frames represent? [blank_start]answer[blank_end] seconds
• 0.5

### Question 3

Question
On your graph, neatly draw a line that you can use to determine the average velocity of the ball between 0.5 s and 2.0 s, then perform the necessary calculations using this line. In the field below, enter your calculated value of the average velocity of the ball. [blank_start]answer[blank_end] metres / second.
• 0.56

### Question 4

Question
On your graph, neatly draw the appropriate line that will enable you to determine the instantaneous velocity of the ball when it is at a position of 0.40 m. Enter the instantaneous velocity below. [blank_start]answer[blank_end] metres/second
• 0.6

### Question 5

Question
The drawing shows the motion diagram of a car that has been photographed at equal time intervals. The dot represents the position of the front of the car. The description that could describe the motion of the car is:
• The car is moving to the left, first speeding up and then slowing down.
• The car is moving to the right, first speeding up and then slowing down.
• The car is moving to the right and slowing down.
• The car is moving to the right and speeding up.

### Question 6

Question
The drawing shows the motion of a car that has been photographed at equal time intervals. Assume that the car is moving toward the right. The Position versus Time graph that could match the motion of the car is:

### Question 7

Question
What is the average velocity of the car between 2.5 s and 7.5 s?
• 1.0 m/s
• 2.0 m/s
• 3.0 m/s
• 4.0 m/s

### Question 8

Question
The Position versus Time graph of a car is shown at the left: What do you need to do to determine the instantaneous velocity of the car at 5 s?
• Draw a tangent line at 5 s and calculate the slope of the line.
• Draw a secant line between 0 seconds and 10 seconds and calculate the slope of the line.
• Draw a secant line between 0 seconds and 10 seconds, calculate the slope and divide it by 2.
• Read the position value that corresponds to 5 s and divide it by 5.

### Question 9

Question
The graph below describes the motion of a car. Which of the following are correct verbal descriptions of the car's motion? Select TWO choices.
• The car is definitely moving to the right.
• The car is definitely moving in the positive x-direction.
• The car is definitely slowing down.
• The car is definitely speeding up.

### Question 10

Question
It is observed that a car traveling toward the south on a straight highway is slowing down. Which of the following statements must be true? There are two correct statements.
• The velocity and speed are both positive
• The velocity vector is directed south
• The acceleration vector is directed south
• The acceleration vector is directed north
