Question: On a safari, you are spear fishing while wading in a river. You observe a fish gliding by you. If your line of sight to the fish is 68.0° below the horizontal in air, and assuming the spear follows a straight line path through the air and water after it is released,
Part A: Determine the angle below the horizontal that you should aim your spear gun in order to catch dinner.
I need help to solve the above question and assume the spear gun barrel is 1.60 m above the water surface, the fish is 1.00 m below the surface, and the spear travels in a straight line all the way to the fish.
