Question

which of these is an example of negative acceleration (or deceleration)? a bird taking off for flight a baseball released by a pitcher an airplane following a straight flight path a car approaching a red light

Explanation:

Negative acceleration (deceleration) occurs when an object's speed decreases, meaning its acceleration is opposite to its direction of motion. A car approaching a red light will slow down to stop, so its speed decreases over time. A bird taking off speeds up (positive acceleration), a baseball from a pitcher speeds up initially (positive acceleration from the throw, then decelerates from air resistance but this is not the primary motion described), and an airplane on a straight path at constant speed has zero acceleration.

Answer:

D. a car approaching a red light
