## 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.
