# Problem 4-54 - Projectile - Part 2 - A

A child throws a snowball straight toward a tree with a horizontal velocity of $18\; m/s$. The tree is $9.0\; m$ away and the snowball starts from a height of $1.5\; m$ above the ground.

(a) How long will the snowball take to reach the tree?
(b) At what height above the ground will the snowball hit the tree?
(c) What is the snowball's velocity as it hits the tree?
[Ans. (a) $0.50\; s$   (b) $0.3\; m$   (c) $19\; m/s\; 15^\circ$ down from the horizontal]

Accumulated Solution

Correct!

The other equally good one is (C), which is the one we will use in our solution. (It would be a very good idea to do the solution all over again at the end with this choice. You must, of course, get the same answers.)
