A small 1 kg mass is launched from the top of a cliff with
speed V at an angle of 30° above the horizontal. When the mass reaches
the ground, its velocity is directed at 45° below the horizontal. Which
one of the following choices is the magnitude of the total impulse that
was imparted to the mass during its flight ? Ignore air resistance.
