Answer:
(c) position
Explanation:
From the work-energy theorem, the workdone by a force on a body causes a change in kinetic energy of the body.
But, remember that the work done (W) by a force (F) on a body is the product of the force and the distance d, moved by the body caused by the force. i.e
W = F x d
This distance is a measure of the position of the body at a given instance.
Therefore, the work done is given by the force as a function of distance (or position).

Answer:
The plane would need to travel at least  (
 ( .)
.)
The  runway should be sufficient.
 runway should be sufficient.
Explanation:
Convert unit of the the take-off velocity of this plane to  :
:
 .
.
Initial velocity of the plane:  .
.
Take-off velocity of the plane  .
.
Let  denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation
 denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation  .
. 
Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration  times average velocity
 times average velocity  .
.
The distance that the plane need to cover would be:
 .
.
