A 175lb man, initially at rest at A on a floating platform, starts walking to the right with a constant speed Vo=3 ft/s relative to the platform until he reaches the right end of the plateform at B. The plateform is attached to the pier by a rope that is initally slack but that becomes taut before the man reaches B. Neglecting any resistance to the motion of the plateform due to the water, determine the impulse provided to the person/plateform system by the rope when the rope becomes taut.
