'Exercise #2
A slow projectile of negligible size and mass m is launched in J viscous fluid environment_ aiming at a point target located at J distance d, as shown in the Figure: The initial kinetic energy of the projectile is Ko mgl /2, where ( = 2d V3: All the quantities mentioned so far are assumed to be known. Neglecting buoyancy and fluid resistance, find: a) The values of the elevation (the initial angle 0 that the projectile axis forms with the horizontal direction) that allow to hit the target
