A cannon on the Bismark German Battleship, fires a 2000 lbs (907kg) shell at an angle of 40degrees. It travels a distance of 20 miles (32.2km), what is the speed of the shell leaving the cannon? What is the variable t?

Like I said this is a very important problem that I need to solve for my Honors Senior Physics class.

Lemme show what I think I know.

Theta = 40 degrees

m = 2000lbs (907kg)

d = 20mi (32.2km)

a = -9.8 m/s^2 (acceleration due to gravity?)

vi = Initial velocity is equal to 0

t = ???

W = weight is equal to 9.8 x 907000g ?

netF = -9.8 x 907 kg?

Please correct me where I am wrong, and show me what is needed and how I figure this problem out. I was told I need no outside information such as information detailing the German battleship.
