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.

Rural Colo. school allowing teachers to carry handguns. BRIGGSDALE, Colo. â A rural school here will allow teachers to carry concealed guns to keep students safe. Briggsdale School, which educates students from preschool to 12th grade, is about a 20-minute drive from the nearest police station, administrators say. And that's a problem if a shooter were to target the school. 1  STORY: Teachers not gung-ho on guns at school. STORY: Classes train teachers on guns.  2 Twenty minutes is a long time, said Superintendent Rick Mondt of the Briggsdale School District, which has about 160 students 65 miles northeast of Denver.
