A cubical box 1m on an edge, open at the top and half filled with water, is placed on an inclined plane making a 30° angle with the horizontal. The box alone weighs 500N and has a coefficient of friction with the plane of 0.30. Determine the acceleration of the box and the angle the free water surface Ans. ax = 2.0394 m/s?, ay = -1.178m/s? makes with the horizontal.
