Last question, can someone help please?

Answer may very but include: The terminal velocity of an object falling through a fluid is its maximum attainable velocity in the fluid. it is said to occur when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. At terminal velocity, the object stops accelerating and moves at constant velocity.

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade
