The situation that describes a negative acceleration is: a runner slowing down at the end of a race.
a swimmer moving at a constant velocity
Why? Because they're just swimming along, not accelerating or decelerating. It's like they're stuck in neutral, not speeding up or slowing down. Just kind of treading water, if you will.
The situation that describes a negative acceleration is when a runner slows down at the end of a race.
The situation that describes a negative acceleration is when a runner is slowing down at the end of a race.
Acceleration is the rate at which an object changes its velocity. When an object, such as a runner, slows down, it means that its velocity is decreasing over time. This means that the acceleration is negative because it is in the opposite direction of the object's velocity.
To determine the acceleration, you can calculate the change in velocity and divide it by the time taken for that change. If the final velocity is smaller than the initial velocity (i.e., the object is slowing down), then the acceleration will be negative.
