Question

A large person and a small person wish to parachute at equal terminal velocities. The larger person will have toa)Jump first from the planeb)Pull upward on the supporting strands to decrease the downward net forcec)Jump lightlyd)Get a larger parachutee)Get a smaller parachute

Answer 1

Answer:

The larger person will have to get a larger parachute. The answer is D

Explanation:

If the smaller person does nothing, the larger person subsequently accelerate for more time and with larger terminal velocity. In this case the person needs to do something so as to reduce the terminal velocity and can also effectively raise the air resistance. For this reason the person should get a bigger parachute. The air resistance in the opened parachute overwhelms the downward force of the gravity. Whereas the net force as well as the acceleration of the person is upward. The bigger parachute has the ability to grab the greater force. If the parachute, dragging force works in the opposite to that of the force of the gravity, hence the drag force slows the parachute decrease as they fall.
