**1. Homework Statement**

a 3 kg ball is dropped from rest from the roof on a building 176.4 m high. While the ball is falling, a horizontal wind exerts a constant force of 12 N on the ball?

Part 1) How long does the ball take to hit the ground?

Part 2) How far from the building does the ball hit the ground?

Part 3) When the ball hits the ground, what is its speed?

**2. Homework Equations**

**3. The Attempt at a Solution**

y=176.4

Vf=?

Vi=0

a=9.81

Part. 3) Vf^2=Vi^2+2ay

Vf= 58.83 m/s

Part. 1) Vf=Vi+at

t=5.99

I don't understand how to find Part 2 because its falling under free fall acceleration so wouldn't it just fall straight down? and the equation to find the x=ViT but the Vi=0 so would'nt the ball just fall straight down instead of falling far away from the building?
