You and a friend are camping. You want to hang a food pack from a high tree branch in order to protect your food from
bears. You attach a stick to a rope and you prepare to throw
it over a tree branch. How hard do you need to throw the
stick?
Use a vertical motion model: h= -16t2 + vt + s where h is the
height you are trying to reach, t is the time in motion, v is the
initial velocity and s is the initial height.
Let's assume...
Your height: 6 feet
Branch height: 20 ft.
Predict what velocity you need to throw the rope
