A peregrine falcon, of mass mf = 0.800 kg, dives at 315 km h to catch a duck of mass ma
= 1.20 kg flying horizontally due west at 70.0 km h-1. The peregrine falcon is flying due east and diving at an angle of 60° to the horizontal. The birds collide and stay together after the collision. What is their speed right after the peregrine falcon catches the duck? Give your answer to three significant figures in m s as a number without the units.
