Question
Which of the following is true for the sections A and C of the graph shown below?
- The velocity is positive in A and negative in C
- The velocity in A is equal in magnitude and opposite in direction from the velocity in C
- The velocity in A is equal in both magnitude and direction to the velocity in C
- The velocity in A is unequal in magnitude but in the same direction as the velocity in C
Hint:
The velocity of A is equal in both magnitude and direction to the velocity in C
The correct answer is: The velocity in A is equal in both magnitude and direction to the velocity in C
In the section A and C of the graph, the slope is positive
Hence the magnitude and direction of velocity in A and C are the same.
