A man with a height of 1.8m stands in a room masturbating. A 12 year old girl with a height of 1.5m is kneeling 1.0m away with her mouth open. Upon orgasm, semen is ejected at a velocity of 10.0m/s. Assuming g = 9.81m/s2, ρ = 1.2kg/m3, and cd = 2.0, at what angle must the man aim his penis to deposit his semen in the girl's mouth?
