Let: u be the speed of projection, a be the inclination of the hose above horizontal, s be the horizontal distance, h be the vertical height, t be the time, g be the acceleration due to gravity. Horizontally: s ut cos(a) (1) Vertically: 0 ut sin(a) - gt^2 / 2 0 t(u sin(a) - gt / 2) Initially, t 0. On landing, t 2u sin(a) / g Susbstituting this value for t in (1): s u^2 sin(2a) / g sin(2a) gs / u^2 sin(2a) 9.81 * 2.0 / 6.3^2 a 14.8 deg or 75.2 deg to 3 sig. fig.
Yes. Get a dog. They will detect a third person AND be friends with the first two when you feel lonely.
