## Homework Statement

Skydiver #1 from the University Skydiving Club steps out of a plane when it is 1 miles above the ground and 10 seconds later skydiver #2 steps out of a plane (at the same height).

They both want to land on the ground at the same time.

To make an estimate assume that a skydiver falls with a constant acceleration of 32ft/sec before the parachute opens and once the parachute has opened the skydiver falls with a constant velocity of 12 ft/sec.

If skydiver #1 opens his parachute 2 seconds after stepping out of the plane, how long should skydiver #2 wait before opening her parachute ?

(You may need to solve a quadratic equation)

## Homework Equations

yf=y0+(v0*t)-(.5gt^2)

## The Attempt at a Solution

i just need a few hints. i think i can solve it.

is this a linear problem or a quadratic problem ?
