Question

When a parachutist jumps from an airplane, he eventually reaches a constant speed, called the terminal velocity. This means that

A) gravity is no longer acting on the parachutist.
B) the force of air resistance is equal to the weight of the parachutist.
C) the force of air resistance is equal to zero.
D) the acceleration is equal to g.

Answer 1

The answer is B.

A is false because gravity will always act on the parachutist.
C is falce because the air resistance will only be equal to zero when the parachutist has a velocity of zero.
D is false because at terminal velocity the parachutist is no longer acceleration, so acceleration equals zero

Answer 2
