i mean horizontal surface not horizontal force..sorry..

What is the third–degree polynomial function such that f(0) = –18 and whose zeros are 1, 2, and 3

Vectors
The magnitude multiplied by the direction should be the same on both sides. So for the boy, it would be (65 kg x 0.6)= 39. Therefore the mass of the girl multiplied by the distance should equal 39 as well. So (39=X x 40). x = 0.975
