Homework Statement
A 72 kg person escapes from a burning building by jumping from a window 30 m above a
catching net. The acceleration of gravity is 9.81 m/s2. Assuming that air resistance is simply a
constant 88 N force on the person during the fall, determine the person’s velocity just before hitting the net.
Homework Equations
Fg (force of gravity) - Air resistance = (mass) (acceleration)
Vf^2 = Vi^2 + 2ax
The Attempt at a Solution
I think the only reason that I am getting the question wrong is because of the fact that I think that inital velocity of the man jumping out is 0. I'm pretty sure that I plugged in everything on the first equation correctly, but I'm geting frustrated.
