Question

If you jumped out of an airplane, you would begin speeding up as you fall downward, due to wind resistance, your velocity would become consistant with time. After this occurs, the magnitude of the force of wind resistance is
a) equal to the force of gravity acting on you
b) is slightly smaller than the force of gravity acting on you
c) is greater than the force of gravity acting on you
d) is much smaller than the force of gravity acting on you

Answer 1

Explanation:

If a person jumped out of an airplane, the weight of the person is greater than the air resistance initially.

As the person moves with constant velocity, it means the final velocity is equal to the initial velocity. The change in velocity is equal to zero . As a result, the net force acting on it is zero.

As the same time, the force of wind resistance is equal to the force of gravity acting on the person. Hence, the correct option is (a).
