An air tanker flies horizontally at an altitude of 180 m and a speed of 80 m/s over a forest fire. In

order to hit its target with flame retardant chemicals, how far before it is directly over the target should it

release its load? Neglect air resistance.

Using Projectile motion equations

for the horizontal distance, I set it = to x = (80m/s)(t)

for the vertical distance i used y = y' + vy't - 1/2gt^2 getting y = 180 - (.5)(10 m/s^2)(t^2)

I set them equal to each other

(80m/s)(t) = 180 - (.5)(10 m/s^s)(t^s)

solved for t and got 2 seconds.

Am i doing things right so far or did i mess up somewhere? Thanks in advance?
