Answer :
The final velocity of the airplane is 70 m/s.
Velocity is the directional velocity of an object in movement as a demonstration of its price of exchange in function as found from a specific body of reference and as measured by using a specific well-known time.
Speed is the time fee at which an item is shifting along a direction, at the same time as velocity is the rate and route of an object's movement. placed any other way, speed is a scalar cost, whilst pace is a vector.
Speed is the velocity at which something moves in a selected course. for example as the velocity of a car traveling north on a highway, or the velocity at a rocket travels after launching. In the scalar manner, the absolute price value of the rate vector is continually the velocity of the motion.
Calculation:-
v = u + at
= 0 + 5 × 14
= 70 m/s
