i think this is just subtitution for dm=ρπr2dx. I'm confused

suppossed initial velocity as Vo and angle is θ. horisontal displacement = Vo cosθ t. so that Vo cosθ = 40/23. vertical displacement = Vo sinθt - 1/2 g t2. so that Vo sinθ = 329/46 (for g=10). by comparison with Vo sin θ and Vo cos θ obtained tan θ = 4,1. in such a way that θ = tan-1 4,1. and Vo...
