111. (a) At the top of its flight, the vertical component of the velocity vanishes, and the horizontal component (neglecting air friction) is the same as it was when it was thrown. Thus, Km v x top kg m s == ° 1 2 1 2 0 050 8 0 30 2 2 .. c o s bg b g ch = 1.2 J. (b) We choose the point 3.0 m below the window as the reference level for computing the potential energy. Thus, equating the mechanical energy when it was thrown to when it is
