Airplane A, starting from rest with constant acceleration, requires a runway 400 m long to become airborne. Airplane B requires a takeoff speed twice as great as that of airplane A, but has the same acceleration, and both planes start from rest.

a) How long must the runway be for airplane B?
Answer for this part was 1600 meters! What is part B?

b) If airplane A takes time 'T' to travel the length of its runway, how long (in terms of 'T') will airplane B take to travel the length of its runway?
