Homework Statement
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?
Homework Equations
d=Vi(t)+(1/2)at^2
a^2+b^2=c^2
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.
