    1. The problem statement, all variables and given/known data
    One body whit m=50kg is pulled whit a acceleration a=2m/s2 on an horizontal plane whit an unknow force F which is making whit the plane an angle of 30 degree
    The friction coeficient betwen the body and plane is [tex]\mu[/tex]=0.2.Find the size of the force F.


    I need to find the size of force acting on the body

    Well i tried to calculate the force whit Newton's formula F=m*a;
    Then whit force compontents on Ox,Oy
