Physics Work, Energy, Power and Collision Mix MCQ (Single Correct)

A semicircular wedge of mass M is placed on horizontal floor. A man of mass 'm' starts moving on wedge from position 'A' with constant speed 'v' relative to 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-

Speed of wedge will first increase then Decrease

Net work done by contact force between man & wedge on system containing man & wedge during the walking of man is zero

Wedge will get displaced by

towards left after man reaches at C

Speed of wedge will be maximum when man reaches at B
