A squirrel sees a BIG acorn being thrown from a tree by a chipmunk and attempts to snatch it. The acorn is thrown from a 10.0 m high branch and with a horizontal velocity of 1.1 m/s. The squirrel on the ground is 5.0 m from the base of the tree. What is the of the squirrel’s average velocity if it grabs the acorn in its mouth just as it touches the ground?

I need this in by 9 minutes.. can someone help?
it takes about √2 sec for the acorn to reach the ground
the direction the acorn is thrown, relative to the squirrel's position is a big factor
... the question is a little vague

h = 0.5g*t^2 = 10m.
4.9t^2 = 10,
t = 1.43s. = Fall time.
d = V*T = 1.1 * 1.43 = 1.57m from base of tree.
d = V*t = 5-1.57 = 3.43m.
V*1.43 = 3.43,
V = 2.40 m/s.
