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.

Best ResponseYou've already chosen the best response.1I 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^2Vi^2/ 2d=a 62^2/(2)(1500)=a a= 1.28 m/s^2

Best ResponseYou've already chosen the best response.1How is it possible? I do not have Fnet to calculate it. Fnet  Ff= Ft

Best ResponseYou've already chosen the best response.1I got it! when we get value of a. 1.28 x 15000 kg = Fnet Fnet  Ff = Ft True?

Best ResponseYou've already chosen the best response.2Considering the thrust is the applied force, looks good!
