title: python calculate distance with height angle and original velocity
body: <p>I am working on python code and I was trying to calculate distance of an object if the height , angle and original velocity was given. this was my code. It doesn't work it gives me an error message every time. </p>
  
  <pre><code>import subprocess as sp
  import math
  sp.call('cls',shell=True)
  pangle = float(0.0)
  distance = float(0)
  a = float(0)
  y = float(0)
  v = float(0)
  a = input("Angle:")
  y = input("Hight (Meter):")
  v = input("Speed (M/S):")
  try:
      a = float(angle)
      y = float(hight)
      v = float(speed)
  except:
      sp.call('cls',shell=True)
      print("Error")
      error = input("")
      exit
  distance = float((v * (math.cos(math.radians(a/1))))*(v * math.sin(math.radians(a)) + ((v * math.sin(math.radians(a)))^2+2*y)**(1.0/2)))
  sdistance = str(distance)
  print ("Distance is " + sdistance + " Meter")
  error = input("")
  exit
  </code></pre>
  
  <p>Please Help</p>
