Thelma and Louise drive their '66 T-Bird convertible off a cliff. They are going 25.9 m/s and the cliff is 97 meters high. Find the magnitude of their velocity vector the moment they impact the ground. Make sure you do the following in your answer:

DO NOT include units. We'll deal with that in the next question.

Give precision to tenths (#.#).

Make your answer correct to within 0.2

so given y is -97, and vi is 25.9 m/s

equations for horizontal projectile motion for vf are

vyf=-g(t)

vf=sqrt of (vxf^2+vyf^2)

so far for t i had 4.447seconds

____

\/-2*-97

----------= 4.447

9.81

and had vyf as -44.6m/s
