# Homework Help: Physics

Posted by Joelle on Wednesday, September 22, 2010 at 9:11am.

A fox sees a piece of carrion being thrown from a hawk's nest and rushes to snatch it. The nest is 14.0 m high and the carrion is thrown with a horizontal velocity of 1.5m/s. The fox is 7.0 m from the base of the tree. What is the magnitude of the fox's average velocity if it grabs the carrion in its mouth just as it touches the ground.
Assume no air resistance and a(y) =g=9.81m/s

1.7 m/s
3.5 m/s
4.2 m/s
2.6 m/s

I'm tried this several times and I'm not coming up with the answer. I've tried cos and sin-I'm not sure what I'm doing wrong

I am not going to work if for you. Here are the steps.

Find the time it takes something to fall 14 meters.
During that time,how far horizonally does it go, given horizontal velocity.
Now for the fox: How fast does he have to go to cover the 7 m in the falling time?

One of the answers is very close.
