## Homework Statement

Someone at a third floor window (12m above ground) hurls a ball downward at v=25m/s and a 45 deg angle. How fast will this ball be traveling when it strikes the ground?

## Homework Equations

d = v(i)t + 0.5at^2

D(y) = -12m

A(y)= -9.81m/s

Vi(y)= 0

## The Attempt at a Solution

Our first attempt at a solution was to find the time. Then we didn't know where to go from there.

(2 x -12)/-9.81=t^2= take the root of whatever that was and get...... 1.5641s
