1. ### Physics homework help

thats where i got my equation from. d = 1/2at1^2 therefore, t1 = sqrt(2d/g) and t2 = d/v(sound) t1+t2=t(total) therefore, (d/v)+sqrt(2d/g) = t(total) it's the rest of it i get messed up on, I've tried it severl times, and it appears you are hinting at this equation, a little insight?
