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.

The CPS school year is made up of 170 classroom instructional days. High schools get 421 minutes or about 7 hours in a school day, while the elementary school day is 354 minutes or 5 hours and 45 minutes long, CPS spokesman Bobby Otter said. The amount of time in the elementary school day is the number being used by Emanuel and the media in reference to the short length of the district's academic day.
