What Are the Equations for Equilibrium and Motion in Physics Problems?

[QUOTE="SteamKing, post: 4544619, member: 301881"] For Problem 2, you are not applying the equations of motion correctly. For the first part of the takeoff, the jet accelerates at a constant velocity for a fixed amount of time. It's not stated explicitly, but you should assume that when t = 0, the position of the jet s = 0 and the velocity of the jet v = 0. Applying the constant acceleration of 4 m/s^2 over the time interval of 5 sec. should give you the velocity directly at the end of this interval. You can also determine how far the jet has rolled in this time. This distance is part of the total distance required for takeoff. Once the jet is rolling and the engines are throttled to max. thrust, then you have a situation where there is an initial velocity and a known acceleration and you have to find the time required to reach takeoff v = 300 m/s and find the distance it takes to reach this velocity.
