An object is launched upwards along an inclined plane at an angle ̘ from the horizontal direction, sliding from the base of the plane. The acceleration due to gravity is g. Neglecting friction and considering that the motion takes place along the straight line that has the steepest slope on the plane, what is the magnitude of the object's resultant acceleration?
g / cos ̘
g cos ̘
g / sin ̘
g
g sin ̘
