## Resource summary

### Question 1

Question
A bike rider is moving along a straight road as shown on the left: Rank the magnitude of the instantaneous acceleration of the biker at the time indicated by the points on the graphs.
• B>A=C
• B>A>C
• A>B>C
• A=C>B

### Question 2

Question
A galloping horse has a speed of 12 m/s at t= 0. After 50 s its speed is 8 m/s. Draw a Velocity-Time graph on your own paper to represent the motion of the horse and use the graph to answer the following two questions. Assume that the acceleration of the horse is uniform. Use your graph to calculate the displacement of the horse. Which value below is the correct?
• 100 m
• 200 m
• 400 m
• 500 m

### Question 3

Question
Use your graph from the previous question to calculate the average acceleration of the horse. The correct value is:
• - 0.8 m.s^-2
• + 0.24 m.s^-2
• - 0.24 m.s^-2
• + 0.8 m.s^-2

### Question 4

Question
The Acceleration versus Time graph represents the motion of a hockey player. Use the graph to determine the change in velocity of the player from 2 to 16 s. The correct value is:
• 0 m/s
• 4.0 m/s
• 5.6 m/s
• 6.4 m/s

### Question 5

Question
A tennis ball is thrown up in the air and caught on the way down. A student draws the following graphs that show the Velocity versus Time of the motion of the ball. Which graph shows the greater magnitude of the displacement of the ball?
• Graph B shows greater magnitude of displacement than Graph A
• Graph A shows greater magnitude of displacement than Graph B
• Graphs A and B show the same magnitude of displacement
• Magnitude of displacement cannot be determined from these graphs

### Question 6

Question
The Velocity versus Time graph below was created with data from a video. Is the object speeding up, slowing down, or changing direction at each of the following times? At t=1s, the object is [blank_start]slowing down[blank_end]. At t=3s , the object is [blank_start]speeding up.[blank_end] At t=5.5s, the object is [blank_start]changing direction.[blank_end]
• slowing down
• speeding up
• changing direction
• speeding up.
• slowing down.
• changing direction.
• changing direction.
• slowing down.
• speeding up.
