A 1.20 kg falcon is diving at 22.0 m/s at a downward angle of 35°. It catches a 0.290 kg dove from behind in midair. What is their combined velocity after impact if the dove's initial velocity was
4.00 m/s directed horizontally? Note that v, is a unit vector pointing in the direction in which the falcon is initially flying. (Enter the magnitude in m/s and the direction in degrees below the
horizontal.)
