need help writing a parametric function for a scene in spider man movie - math project

Question

precal · Answer

Spider height is 152 meters (I guess he is on a building)

precal · Answer

He is trying to catch a person who fell, all I know is that the person falling is at 76 meters

precal · Answer

Their paths cross at 38 meters.  Need to write a parametric function to detemine if spiderman catches the falling person

let me try once. :) |dw:1432038044970:dw|

loser66 · Answer

To Spider man: Let $H_s$ is the height of spider man, then $H_s = \dfrac{1}{2}V_s t^2+V_{0s}+152$ but $V_{0s}=0$, hence it is .... your turn

precal · Answer

I was going to use the following formulas for parameters
x=(vcos(theta))t
y=(vsin(theta))t-16t^2+152

loser66 · Answer

Those are parametric equation of both them with respect to t.

loser66 · Answer

They fall, not be shooted from a canon, the velocity is straight vertical, no cos/sin here

precal · Answer

I also, know the time they both hit the ground (ok maybe I should say are at ground level)
Spider man is on the ground at 8.95 seconds
and the falling person is on the ground at 13.71 seconds.
We took the time from the movie scene.

precal · Answer

ok so I need to use another set of parametric functions.  Let me look those formulas up

thanks for your help.
