Q- A wedge of mass km is placed on a smooth horizontal surface. The inclined face of the wedge makes an angle θ with the horizontal surface. A small block of mass m is placed on the inclined surface and released. The friction between the block and inclined surface is μ. (a) If the acceleration of the block relative to the wadge is a, find acceleration of the wadge. (b) If to a stationary observer the acceleration of the block appear in a straight linen making an angle 450 with the horizontal find the angle θ (in terms of k).
