Question

the speed at which the acceleration of a falling object stops because air resistance balances the objects weight. terminal speed constant speed instantaneous speed average speed

Explanation:

When air resistance balances the weight of a falling object, its acceleration becomes zero and it reaches a steady - state speed called terminal speed. Constant speed just means speed doesn't change but doesn't imply the specific condition of air - resistance and weight balance. Instantaneous speed is the speed at a particular moment. Average speed is the total distance divided by total time.

Answer:

A. terminal speed
