Identify the correct direction of the velocity and acceleration vectors of a cyclist.
Understand the Problem
The question asks us to identify the correct direction of the velocity and acceleration vectors of a cyclist from a provided motion diagram.
Answer
The second option is correct.
The final answer is the second option, where ( v_f ) is to the right, ( v_i ) is to the left, ( \Delta v ) is to the right, and the acceleration vector ( a ) is to the right.
Answer for screen readers
The final answer is the second option, where ( v_f ) is to the right, ( v_i ) is to the left, ( \Delta v ) is to the right, and the acceleration vector ( a ) is to the right.
More Information
In the diagram, the cyclist moves from left to right, causing the velocity vector to point to the right. The change in velocity ( \Delta v ) and acceleration ( a ) vectors also point in the direction of motion (right) as the cyclist accelerates in that direction.
Tips
Confusing directions of initial and final velocity can lead to mistakes. It's important to follow the direction of motion and determine vector changes.
