Ajet plane is cruising at 300 m/s when suddenly the pilot turns the engines up to full throttle. after traveling 4.0 km, the jet is moving with a speed of 400 m/s. what is the jet’s acceleration as it speeds up?

8.75 m/s^2

Explanation:

initial speed, u = 300 m/s

final speed, v = 400 m/s

distance, h = 4 km = 4000 m

Let a be the acceleration of the plane.

Use third equation of motion

a = 8.75 m/s^2

Thus, the acceleration of the plane is 8.75 m/s^2.
