A vector A~ has a negative x component 2.89 units in length and a positive y component 3.17 units in length. The vector A~ can b
1 answer:
Answer:
a1 = -2.89 units
a2 = 3.17 units
magnitude = 4.2896 units
direction = 132.35 degrees
Explanation:
We can write the vector in component form as: <-2.89, 3.17>
That means that its i and j components are:
a1 = -2.89 units
a2 = 3.17 units
The magnitude of the vector is given by:
The vectors direction can be found from the tangent function, ad noticing that the vector must reside on the Second Quadrant:

Answer:
L/D= 112
Explanation:
Aerodynamics can be defined as the branch of dynamics which deals with the motion of air, their properties and the interaction between the air and solid bodies.
Aerodynamics law explains how an airplane is able to fly. There are four forces of flight, and they are; lift, weight, thrust and drag. The amount of lift generated by a wing divided by the aerodynamic drag is known as the lift to drag ratio.
Lift increases proportionally to the square of the speed.
The solutions to the question is the file attached to this explanation.
Lift,L= qC(l). S---------------------------(1).
and,
Drag,D = qC(d).S ----------------------(2).
Hence, Lift to drag ratio,L/D= C(l)/C(d).
Therefore, we have to compute various angle of attack.(check attached file)...
Then, (L/D) will then be equal to 112.
