Physics 11 Question! An airplane has 1500 m to accelerate to a speed of 62.0 m/s to take off. If it experiences 15000 N of friction calculate the thrust of the engines. Mass of airplane is 15000 Kg.

    I do not understand what is it asking me to find. It says " Calculate the thrust of the engines", I assume it is talking about acceleration. What do you think? Vf^2-Vi^2/ 2d=a 62^2/(2)(1500)=a a= 1.28 m/s^2

    Thrust in your case is the tension, where the friction opposes it

    T is your thrust here

    How is it possible? I do not have Fnet to calculate it. Fnet - Ff= Ft

    I got it! when we get value of a. 1.28 x 15000 kg = Fnet Fnet - Ff = Ft True?

    Considering the thrust is the applied force, looks good!
