# What's the force?

Classical Mechanics Level 3

There is a box of mass $$6\text{ kg}$$ placed on a smooth inclined plane with angle $$30^\circ$$. What must the acceleration of the wedge be such that the mass does not slip down the plane?

Details 1) The inclined plane is smooth. 2)Take the wedge to be moving.

Assume $$g= 10 \text{ m/s}^2$$.
