The mass of a pigeon hawk is twice that of the pigeons it hunts. Suppose a pigeon is gliding north at a speed of ?P=18.2 m/svP=18.2 m/s when a hawk swoops down, grabs the pigeon, and flies off, as shown in the figure. The hawk was flying north at a speed of ?H=33.1 m/s,vH=33.1 m/s, at an angle ?=45∘θ=45∘ below the horizontal at the instant of the attack. What is the birds' final speed ?fvf just after the attack? ?f=vf= m/sm/s What is the angle ?fθf below the horizontal of the final velocity vector of the birds just after the attack? ?f=θf=

Question
The mass of a pigeon hawk is twice that of the pigeons it hunts. Suppose a pigeon is gliding north at a speed of ?P=18.2 m/svP=18.2 m/s when a hawk swoops down, grabs the pigeon, and flies off, as shown in the figure. The hawk was flying north at a speed of ?H=33.1 m/s,vH=33.1 m/s, at an angle ?=45∘θ=45∘ below the horizontal at the instant of the attack.
What is the birds' final speed ?fvf just after the attack?
?f=vf=
m/sm/s
What is the angle ?fθf below the horizontal of the final velocity vector of the birds just after the attack?
