Answer:
hello your question is incomplete below is the missing part
What is the x component of the bird’s average velocity
answer : 33.926 km/h
Explanation:
Time = 2.82 h
Distance flown by bird = 99.8 km in a direction ; 42.7 degrees east of North ( N.E )
Taking North to be the positive y direction and East to be the positive X direction
Calculating the x component of the birds average velocity
Distance OA = 99.8 km
X component of velocity is expressed as (Vx)= Δx / Δt
looking at triangle ABC ; Δx = (OA) sin∅
Therefore ( Vx ) = [( 99.8 )*sin(42.7°)] / 2.82
= -95.67 / 2.82 ≈ - 33.926 km/h
considering North to be positive y direction and east to be positive X direction. the x component of the velocity will be = 33.926 km/h
