Answer to Question #34774 in Mechanics | Relativity for Ethan Berry

Question

with a mass of 114 kg, Baby Bird is the smallest monoplane ever flown. Suppose the Baby Bird and the pilot are coasting along the runway when the pilot jumps horizontally to the runway behind the plane. The pilot's velocity upon leaving the plane is 5.32 m/s backward. After the pilot jumps from the plane, the plane coasts forward with a speed of 3.40 m/s. If the pilot's mass equals 60.0 kg, what is the velocity of the plane and pilot before the pilot jumps?
