20 g = 20 / 1000 = 0.02 kg.
Magnitude of momentum of the sparrow = mass * velocity
= 0.02 * 8.1
= 0.162 kg-m/s. (answer)
Hey there,

Say the initial point is (0,0)
The final point is
x = 200 + 135*cos(30) = 200 + 135*sqrt(3)/2 = 316.91 ft
y = 135*sin(30) = 135/2 = 67.5 ft
Resultant vector = (316.91, 67.5) - (0,0) = 316.91, 67.5) ft
Then, it jumps to HIGHER ORBITALS
