The W weight of a box on an inclined plane can be resolved in two vectors components. one pararell to the plane and the othe perpendicular to it .
a) at wht angle of the plane relative to the horizontal would the components be equal.
b) at what angle would the perpendicular component equal w
c) at what angle would the pararell componern equal W?
d) assuming negligible friction , what is the acceleration of the box in each of the three cases?
