<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;
- length of the runway, = L
- let the take off speed = V₁
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.

Answer:
Explanation:
Given data:
Mass of the man,
Total mechanical energy,
Height,
Suppose there is no external force acting on the man. In this situation, the total mechanical energy (kinetic + potential) will remain steady.
Let the speed of the man at 2.6 m be <em>v</em>.
Thus,
