the second question :i don't know how to begin !
...
the first question
F=kx, where F is the force applied, k is the spring constant and x is the distance stretched.
k = 800 N/m
x=0.270
F=kx=800*0.270=216N/m
I don't know how to find the total length of the spring ..

Two Physics Problems .. plsss help ??!
Q1 :
The figure shows a mass M inside a tube bent in a circle of radius R=1.20 m. M can slide with negligible friction inside the tube. The tube rotates about a vertical axis passing through the center. The mass is in equilibrium at q =56.5 degrees...
