Solution: Projectile Motion An object is propelled upward at
Chapter , Problem 8.5.83(choose chapter or problem)
Projectile Motion An object is propelled upward at an angle e, 45 < e < 90, to the horizontal with an initial velocity of Va feet per second from the base of a pl ane that makes an angle of 45; with the horizontal. See the illustration. If air resistance is ignored, the distance R that it travels up the inclined plane is given by the function v 2v2 R(e) = cos e(sin e - cos e) ( a) S how that f f I , .... -'4iI I \ v 2v2 R(e) = [sin(2e) - cos(2e) - 1) , (b) Graph R = R(e). (Use va = 32 feet per second.) " (c) What value of e m akes R the l argest? (Use va = 32 feet per second.)
