SoRry But I Have An a PrOblem To start WIth this.... A boy is at a distance d = 6m from the base of a building attempts to throw a ball through a window size that H = 90cm at a height h = 8m. if the ball's initial speed is v0 = 15m / s, determine the range of initial angles Ø0 allowing the ball passes through the window. (acceleration of the ball is 9.81 m / s ^2 vertical down) How Can I DetErmine the Angles?? http://img411.imageshack.us/img411/5928/123gs.jpg [Broken] ThanKs For The help!!
