Re: Height
(1.25 x 60)/1.68 = 45 kg 
Note: this is mass not weight. We would have to multiply 45 by 9.81 (acceleration due to earths gravity)
45 x 9.81 = 441.45 N (Newtons)

@MoyMarian
JurassicPlank1 may be trying to do your homework for you, but please be careful. For example, JurassicPlank1s solution to this problem
http://www.mathisfunforum.com/viewtopic.php?id=11551
is incorrect.
I suggest you do your own homework instead of copying somebody elses mistakes.
