The area under the curve represents the [blank_start]________________[blank_end] of the cart from zero until six seconds.
Answer
-
displacement
Question 5
Question
If you were to draw an Acceleration versus Time graph for this motion, which of the following would best describes the slope of your graph?
Answer
-
positive slope
-
negative slope
-
zero slope
-
variable, as the graph is a parabola

Area = [blank_start]1.2[blank_end] m/s
Answer
-
1.2
Question 7
Question
A biker is moving along a straight road as shown.
The three graphs represent the motion of the biker during three training exercises, A, B, and C.

Question 8
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.
Answer
-
100 m
-
200 m
-
400 m
-
500 m
Question 9
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 average acceleration of the horse.
Answer
-
– 0.08 m/s^2
-
+ 0.08 m/s^2
-
+ 0.24 m/s^2
-
– 0.24 m/s^2
Question 10
Question

Use the graph to determine the change in velocity of the player from 2 to 16 s.
Answer
-
0 m/s
-
4.0 m/s
-
5.6 m/s
-
6.4 m/s
Question 11
Question
A tennis ball is thrown up in the air and caught on the way down. A student draws the two graphs (A and B) that show the Velocity versus Time of the motion of the ball. Which graph shows the greater magnitude of the displacement of the ball?
Image:
Slide2 (binary/octet-stream)
Answer
-
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
