Question: a 1 2 . 0 kg box rests on an incline that makes an angle with the horizontal 1 8 degrees. A hand pulls on

a 12.0kg box rests on an incline that makes an angle with the horizontal 18 degrees. A hand pulls on a string attached to the box at an angle of 12 degrees above the tilted x-axis of the inclined coordinate system. The coefficient of static friction between the box and surface is 0.38 and the coefficient of kinetic friction is 0.22. If the force of the hand pulling on the string is 40.0N, what is the acceleration of the box?
