Ajet plane has a takeoff speed of 75 m/s and can move along the runway at an average acceleration 1.3 m/s squared. if the length of the runway is 2.5 km, will the plane be able to use this runway safely?

Explanation:

Initial speed of the jet, u = 0

Final speed of the jet, v = 75 m/s

Average acceleration of the jet,

Length of the runway, l = 2.5 km = 2500 m

Let d is the distance covered by the jet. Using the third equation of motion as :

d = 2163.46 m

or

d = 2.16 km

As the value of d is less than the length of the runway, so the aircraft will be safe.
