Answer:
The truck must travel by 95.16 km/h to stay beneath the airplane
Explanation:
Lets explain how to solve the problem
How fast must a truck travel to stay beneath an airplane that is moving
105 km/h at an angle of 25° to the ground
The truck moves a long the horizontal ground
The airplane moves 105 km/h at an angle 25° to the ground
The truck must moves with velocity equal the horizontal component
of the velocity of the airplane to stay beneath the airplane
The angle between the line represented the velocity of the airplane
and the ground is 25°
→ The horizontal component of the velocity = v cos(25)
→ The velocity of the airplane is 105 km/h
→ The horizontal component = 105 cos(25) = 95.16 km/h
The velocity of the truck = the horizontal component of the airplane
<em>The truck must travel by 95.16 km/h to stay beneath the airplane</em>
