Final answer:
The terminal velocity of a parachutist occurs when the force of air resistance is equal to the weight of the parachutist.
Step-by-step explanation:
When a parachutist jumps from an airplane, he eventually reaches a constant speed, called the terminal velocity. At this point, the force of air resistance on the parachutist is equal to the weight of the parachutist. Therefore, the correct answer is E) the force of air resistance is equal to the weight of the parachutist.
