Describe the cyclist’s acceleration.
The acceleration of the cyclist is constant and zero
The acceleration of cyclist is going down
The acceleration of the cyclist is going up
The acceleration of the cyclist is constant and non-zero
The correct answer is "The acceleration of the cyclist is constant and zero." This means that the cyclist is not speeding up or slowing down and maintaining a constant velocity.
The acceleration of the cyclist can be described as either constant and zero if the cyclist is not accelerating or decelerating, or as constant and non-zero if the cyclist is accelerating or decelerating at a constant rate. So, the correct answer would be:
- The acceleration of the cyclist is constant and non-zero
To describe the cyclist's acceleration, we need to understand that acceleration is the rate at which the cyclist's velocity changes over time.
Let's break down each given scenario:
1. If the acceleration of the cyclist is constant and zero, it means that the velocity of the cyclist is not changing. This suggests that the cyclist is maintaining a constant speed and not gaining or losing any velocity.
2. If the acceleration of the cyclist is going down, it indicates that the cyclist is slowing down. This means that the cyclist's velocity is decreasing, and the rate at which it is decreasing is becoming smaller over time.
3. If the acceleration of the cyclist is going up, it means that the cyclist is speeding up. This suggests that the cyclist's velocity is increasing, and the rate at which it is increasing is becoming larger over time.
4. If the acceleration of the cyclist is constant and non-zero, it means that the cyclist's velocity is changing at a constant rate. This suggests that the cyclist is either continuously speeding up or slowing down, depending on the direction of the acceleration (positive or negative).
It's important to note that acceleration can be positive (speeding up), negative (slowing down), or zero (maintaining a constant speed). The specific scenario depends on the given information about the cyclist's acceleration.
