Thanks in advance--
Problem:
A woman who weighs 470 x 10^2 is leaning against a smooth vertical wall, as the drawing shows.
a) Find the force FN (directed perpendicular to the wall) exerted on her shoulder by the wall.
b) Find the horizontal component of the force exerted on her shoes by the ground.
c) Find the vertical component of the force exerted on her shoes by the ground.
I answered the problem, but I was wondering if I did it correctly.
I uploaded the drawing.
a) Fn(sin60)r1 = mgr2
Fn(sin60)(1.1+0.4) = 470(cos60)(1.1)
Fn = 198.99 N
b) 198.99 N
c) 198.99N + 470N = 668.99 N
Thanks!
