    Trouble with Proof of Optimal Launch Angle

    Here is my problem, can anyone help me out? Prove the maximum range of a skier going down a ski jump is given by (theta) = 45degrees - phi/2 , where theta = optimal launch angle , phi = slope angle of take off with respect to the incline of the hill. I have the following equations to use...

    Find Optimum Launch Angle For Distance in Physics Class Project

    My physics class project is to construct a catapult. My question is what is the optimum launch angle for distance. This was posted awhile back by someone else, but i can't find the post again. I think it said that because of air resistance an angle slightly above 45 degrees is optimum for...
