Help on projectile problem

  1. Sep 10, 2008 #1
    any help is much appreciated!!

    Sarah sent a arrow a horizontal distance of 9.5X10^2 m. What was the speed of the arrow at the top of the flight if the arrow as launched at an angle of 45 degrees with respect to the horizontal?

    i figured out the Vi, which was 96.54. But, i'm not sure what to do from there.

    Hi mochilili,

    What did you do to find that initialvelocity? I don't think it is quite right.
