Cannon Problem

Given an angle in radians and an initial velocity (Vo) in meters per second, calculate how far from the 
cannon the shot will first hit the ground (in meters from the cannon.) Use the following formulas: 

  Voy = Vo * sin(angle)
  Vox = Vo * cos(angle)
  y = 1/2*ay*t^2 + Voy*t
  Dx = 1/2*ax*t^2 + Vox*t
  (Hints: y=0, ay=-9.81, ax=0)
Assume that their is no air resistance.

Input:
Input will be multiple lines with an angle in degrees followed by an initial velocity (Vo) given in m/s

Ouput:
The range in meters.
