The length of the new runway In terms of (L) is 4L.
<em />
<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.

I'm not entirely sure, but I believe it is A Friction. because gravity pulls down, weight isn't a force, and acceleration doesn't oppose motion
Answer:
16 m/s , hope this helps.
The correct option is C.
Since the home gets its water from public supply, the best place to get the water quality report is from the local water treatment facility who processed the water. Water quality report is a document which summarizes information about the water sources that are used, detected contaminants, compliance observed, etc.
Answer:
The runner's acceleration as she sped up to the finish line is 0.95m/s²
Explanation:
Acceleration is the change in velocity of a body with respect to time. It is expressed as;
Acceleration = change in velocity/time
Change in velocity = final velocity - initial velocity
Acceleration = final velocity - initial velocity / time
Given initial speed = 8.0m/s
Final speed = 9.9m/s
Time taken = 2.0s
Acceleration = 9.9-8.0 / 2.0
Acceleration = 1.9/2
Acceleration = 0.95m/s²
