Which situation is an example of negative acceleration?
A. A car moving a constant velocity
B. A jogger slowing down at the end of a race
C. A diver jumping off a diving board and falling to the swimming pool below
D. A bicycle increasing its velocity as the rider pedals harder
B. A jogger slowing down at the end of a race
Do believe you are correct with what ypu chosen?
Yes, I believe I am correct with the choice B. A jogger slowing down at the end of a race is an example of negative acceleration because the jogger is decreasing their velocity. Negative acceleration occurs when an object's velocity decreases over time.
The correct example of negative acceleration is B. A jogger slowing down at the end of a race.
The situation that is an example of negative acceleration is B. A jogger slowing down at the end of a race.
To understand why this is an example of negative acceleration, it's helpful to know that acceleration refers to a change in velocity over time. Acceleration can be positive, negative, or zero.
In this case, the jogger is initially moving at a certain velocity during the race. However, as the jogger approaches the end of the race, they start to slow down. This means that their velocity is decreasing over time. Since the velocity is decreasing, the acceleration is considered negative.
To determine the acceleration, you can use the formula:
acceleration = (final velocity - initial velocity) / time
In this scenario, the final velocity of the jogger is lower than the initial velocity, resulting in a negative change in velocity. Hence, this situation represents an example of negative acceleration.
