An aircraft has a mass of 3.10 x 105 kg. At a certain instant during its landing, its speed is 48.2 m/s. If the braking force is 3.40 x 105 N, what is the speed of the airplane 11.9 s later?

Best ResponseYou've already chosen the best response.2Newton:\[F=ma\]Kinematic:\[v=vi+at\]we can get the acceleration of the plane from the first equation, and plug that and the given numbers into the second one to find the velocity after 11.9 seconds (note that acceleration will be in the negative direction here)
