A penis mass m = 200g and 17cm long at rest left in the hair with a speed v = 20m / s. in erection, the penis is 25cm long and only 2/3 goes into the vagina. knowing that the area has the sufficiently lubricated during caresses so friction is negligible. we take g = 10N/Kg. 1-calculate the weight of the penis and its penetration grows. 2-giving nature of the movement of the kidneys of man. 3-a position which was the girl before the First five minuites. . good luck.
