You are sitting in a commercial jetliner. it is on the runway and ready to take off. before it does, clever soul that you are, you hang a .5 meter long string from the ceiling just overhead and attach to its free end a weight whose mass is m = .05 kg. the jet begins its acceleration. as it does, the string and mass swing toward you until the string comes into equilibrium at a constant angle of θ = 26o with the vertical.

a.) what is the jet's acceleration?

b.) once the jet gains altitude and proceeds with a constant velocity, what will the string and mass be doing (that is, will the 26o angle have changed)? explain
