Final answer:
The duration of an adhoc acceleration in physics is not a fixed amount of time and can vary depending on various factors such as the force applied and the initial velocity.
Step-by-step explanation:
In physics, the duration of an adhoc acceleration depends on various factors such as the force applied and the initial velocity. It is not a fixed amount of time and can vary in different scenarios. For example, if an object is subjected to a constant force, its acceleration will last as long as the force is applied. However, if the force is not constant, the duration of the acceleration will depend on the specific circumstances.
