Homework Statement
There is inclined, smooth plane whish is sloped with angle 30 degrees. Some objects moves on it. The attraction power is 17 Newtons. Find the force which gives acceleration for the body.
Homework Equations
F = m×a;
F_attraction = m×g;
L = 30⁰;
F_friction = u×N;
The Attempt at a Solution
X: ma = N×cos(L) + F - F_friction
Y: 0 = F_attraction×sin(L) + N
Now I'm "freezed"
What to do?
