Best Answer: Time of flight t = 2vy/g Distance = vx*t = 2vx*vy/g We must maximize vx*vy as a function of launch velocity v. vx = vcosÎ¸, vy=vsinÎ¸ Thus we must maximize sinÎ¸cosÎ¸. At the maximum, the derivative of sinÎ¸cosÎ¸ = 0. From the ref, the derivative = cos(2Î¸).Thus cos(2Î¸) = 0, 2Î¸ = 90 deg, Î¸ = 45 deg.'d put optimal at a lower angle, say 20 to 30 degrees, to keep most of the air time while reducing the energy lost at landing and improving the horizontal speed component for the post-landing roll.

---- Upon arrival at school, an elementary teacher prepares for the day by organising displays and ensuring resources and worksheets are available. Morning begins with calling the roll, and starting on the first lesson of the day, which is usually maths or a language-based lesson (e.g. reading or writing).here is usually no school cafeteria, as the school day typically ends at around noon or 1:00 pm. (Many schools in the former DDR [GDR] still have cafeterias.) Students go home for lunch, and in the afternoon they usually have a fair amount of homework to do.
