Question

A semicircular wedge of mass M is placed on a horizontal floor. A man of mass m starts moving on wedge from position A with constant speed v relative to the wedge. Initially, both man & wedge were at rest . Neglect the friction between wedge & horizontal surface and man doesn't slips on the wedge while man moves from A to C relative to wedge. The correct statement is, speed of wedge will first increase then decrease, speed of the wedge will remain constant, speed of the wedge first increases up to a maximum value and then remains constant, the wedge doesn't move

The velocity of the wedge = – m v c o s θ m + M θ : Angle made by v → m a n with the horizontal
