Question

During a parachute jump, the person is initially in free fall and then the parachute is opened. While in free fall, there are two forces acting on the jumper-gravity and air fraction. The faster the jumper is at falling, the more air friction there is. At a certain speed, the upward force of air friction is just equal in size to the downward pull of gravity. When this happens, the jumper has no net force on her and therefore she falls at a constant velocity. This velocity is called the "terminal velocity." The force of wind friction on a certain 90kg jumper is calculated using the equation Ff=0.50v^2 where the speed is in m/s and the force is in newtons. Calculate the terminal velocity of this parachutist.

Answer 1

gravitational force is ... m g

0.50 v^2 = m g = 90 * 9.8

Answer 2

Frank how are you still in school its been 13 years since you asked a question that I don't know how to answer. Please Tell me how old are you? What is your phone number? Where do you live? What grade are you even in?

Its unbelievable since 2005 you have been asking questions after questions. The journey still continues till this day.

Answer 3

Also is this Newtons law?

Answer 4

That's not the real Frank. Anyone can put the name "Frank" in.

Stupid. Smh.

Answer 5

Actually, @The guy above me is stupid, I came to this question because I was looking through the original Frank's question history and this is the most recent question he asked.
