A 900-N boy sits on top of a ladder of negligible weight that rests on a frictionless

Question:

A 900-N boy sits on top of a ladder of negligible weight that rests on a frictionless floor as in Figure. There is a cross brace halfway up the ladder. The angle at the apex is q = 30^o.

(a) What is the force exerted by the floor on each leg of the ladder?

(b) Find the tension in the cross brace.
