Answer:
h(t) = -16t2 + 186t + 43
at the ground h = 0
hence; -16t2 + 186t + 43 = 0
solving this quadratic equation using the quadratic formula ; a = -16, b = 186, c = 43 ; x = (-b +-(b2 - 4ac)1/2)/2a
gives t = 11.8 seconds to the nearest tenth (note that the negative root has no practical significance)

I do hope this is right please forgive me if this is wrong.
So the functions are simply the same but the only different among them is when sin x and cos x is shifted by pi/2 as compared to cos x. I hope you are satisfied with my answer and feel free to ask for more if you have questions and clarifications
