Good morning, first post and more than excited that I can get possible help for physics. Only problem I think I have is translating physics problems into soluble questions.
A hammer slides 2.5 m down a smooth roof which has an incline of 15 degrees.
At the instant the hammer leaves the roof, find the magnitude Vo and direction of the angle of its velocity.
x = 2.5 m
angle = 15 degrees
X = Xo + Vot + 1/2at^2
V^2 = Vo^2 + 2a(X-Xo)
X = Xo + 1/2(V+Vo)t
Having two unknowns is leaving me at a halt. Is final velocity [at the instant leaving the roof] 0 m/s? The last equation [X = Xo + 1/2(V+Vo)t] would have V = 0 m/s and Vo = 0 m/s making the entire equation unsolvable.

Homework Equations
