Okay... so we know that the train is moving north, which means the Apposing wind (and Friction) would be coming from the south.
We also know that the wind is coming from the West.
And based upon this information, we know that the Smoke has to be going South West because when an Apposing wind is pushed by a natural wind, the object being affected by both winds moves in both directions (a.k.a. diagonal)...

Answer:
Part 1) Option A. h(2) = 86.00 means that after 2 seconds, the height of the ball is 86.00 ft
Step-by-step explanation:
we have
where
t ----> is the time in seconds after the ball is dropped
h(t) ----> he height in feet of a ball dropped from a 150 ft
Find h(2)
That means ----> Is the height of the ball 2 seconds after the ball is dropped
Substitute the value of t=2 sec in the equation
therefore
After 2 seconds, the height of the ball is 86.00 ft.
