1. The problem statement, all variables and given/known data A hockey puck slides off the edge of a table with an initial velocity of 20 m/s. The height of the table above the ground is 2 m. At what angle below the horizontal does the puck hit the ground? 2. Relevant equations d=Vi(t)+(1/2)at^2 a^2+b^2=c^2 3. The attempt at a solution Horizontal Values: Vi=20Cos(theta), a=0, Xi=0m, Xf=? Vertical Values: Vi=20sin(theta), a=-9.81m/s^2, Xi=2m, Xf=0 1) 2=20sin(theta)t+(0.5)(-9.81)t^2 2)1/10=sin(theta)t+(-4.905)t^2 3) 1/10 x 1/(-4.905)=sin(theta)t+t^2 Stuck after solving that part.
