A slow projectile of negligible size and mass m is launched in a viscous fluid environment, aiming at a point target located at a distance d, as shown in the Figure. The initial kinetic energy of the projectile is Ko = mgt/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. m VO

A slow projectile of negligible size and mass m is launched in a viscous fluid environment,
aiming at a point target located at a distance d, as shown in the Figure. The initial kinetic
energy of the projectile is Ko = mgl/2, where (= 2d/ /3. 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.
