Answer:
The magnitude of the final velocity is 14.14 m/s
Explanation:
The horizontal component of the final velocity and vertical component of the final velocity, forms a perpendicular vector. To determine the magnitude of the final velocity, we sum the two vectors.
To add two perpendicular vector, Pythagoras principle is used.
The magnitude of the final velocity is 14.14 m/s
The length of the new runway In terms of (L) is 4L.

<em>Your question is incomplete, it seems your question is missing the following information below;</em>
"In terms of (L) , what must be the length of the new runway?"
The given parameters;
For the newly designed planes;
the take off speed is double of the original = 2V₁
the acceleration for both take is constant = a
The take off speed for the given constant acceleration is given as;
The length of the new runway In terms of (L) is calculated as follows;
Thus, the length of the new runway In terms of (L) is 4L.
