Answer:
Vy = 4.65 m/s
Explanation:
Since, the airplane is descending at a rate of 480 km/h at an angle of 2° from horizontal. Therefore, its vertical component of velocity shall be given as follows:
Vy = V Sin θ
where,
Vy = Vertical Component of Velocity = ?
V = Velocity of Plane = (480 km/h)(1000 m/1 km)(1 h/3600 s) = 133.33 m/s
θ = Angle = 2°
Therefore,
Vy = (133.33 m/s)(Sin 2°)
Vy = 4.65 m/s
