The speed at which a light aircraft can take off is 120 km/h. (a) what is the minimum constant acceleration required for the plane to take off after it has run 240 meters? (b)how long does it take to take off?

ps. i want a solution. for reference, the answer is )2.32m/s^2 (b) 14.4s

A) a = 2.31[m/s^2]; B) t = 14.4 [s]

Explanation:

We can solve this problem using the kinematic equations, but firts we must identify the data:

Vf= final velocity = take off velocity = 120[km/h]

Vi= initial velocity = 0, because the plane starts to move from the rest.

dx= distance to run = 240 [m]

To find the time we must use another kinematic equation.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
