A 1.20 g spider hangs on its thread from the branch of a tree. A horizontal win blows the spider and the tread to an angle of 35 deg from the vertical. Find the force of win on the sider and the tension in the tread.

2. Relevant equations

Fnet= Fg + Fw + Tcosθ + Tsinθ

3. The attempt at a solution

Fg = mg

Fg= (0.0012 kg)(9.8 m/s^2)

Fg= 0.01176 N

Fnet = 0.01176 N + Fw + Tcos55° + Tsin55°

I got the 55° by subtracting the 35° from 90°

Vertical equilibrium:

0.01176 N = Tsin55°

0.014356 N = T

Horizontal equilibrium:

Tcos55°=Fw

(0.014356 N)(cos55°)=Fw

0.00823 N = Fw
