Question

Find the components of the velocity of an airplane traveling as 119 km/h at an angle of 12 degrees to the ground.​

Answer 1

Step-by-step explanation:

V = 119 km/h

α = 12°

___________

Vₓ - ?

Vy - ?

Horizontal component:

Vₓ = V·cos α = 119·cos 12° = 119·0,9782 ≈ 116 km/h

Vertical component

Vy =V·sin α = 119·sin 12° = 119·0,2079 ≈ 24.7 km/h

Examination:

V = √ ( Vx² + Vy²) = √ ( 116² + 24.7²) ≈ 119 km/h
