(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A projectile is shot from the edge of a cliff 125 m above ground level with an initial speed of 65.0 m/s at an angle of 37 degrrees with the horizontal. Find the horizontal and vertical components of its velocity at the instant just before the projectile hits point P (the ground).

2. Relevant equations

Vxo = Vo cos 37

Vyo = Vo sin 37

Vy = Vyo - gt ...????

3. The attempt at a solution

The answer is given in the back of the book. Plugging in the initial velocity in the first equation gives the correct answer (which I expected), but the answer I acheive for Vyo should be negative and I haven't yet acheived that. I tried to plug the answer I got for Vyo (the positive one) into the equation Vy = Vyo - gt, but still did not get the right answer. I'm truly grasping at straws here.
