Answer:

The truck must travel at a speed of 98.6677 km/hr to stay beneath the airplane

Explanation:

The given parameters are;

The velocity of the airplane, v = 105 km/hr

The direction of the airplane, θ = 25 degrees to the ground = 25°

Therefore, we have that the horizontal component of the velocity of the plane, vₓ is given as follows;

vₓ = v × cos(θ) = 105 km/hr × cos(25) ≈ 98.6677 km/hr

The vertical component of the velocity of the plane, [tex]v_y[/tex], is given as follows;

[tex]v_y[/tex] = v × sin(θ)  = 105 km/hr × sin(25) ≈ 44.37 km/hr

The truck only has to travel at a speed equal to the horizontal velocity of the airplane to stay beneath the airplane

Therefore, the travelling speed the truck must be vₓ which is 98.6677 km/hr to stay beneath the airplane.
