1) A mass m on a massless string of length 1 hangs from the ceiling of a train accelerating with constant acceleration 9/8. a) Find the tension in the string and the angle that the string makes with the vertical if it is hanging in a steady state (i.e. not moving as seen by an observer in the train). b) Suppose the mass is set into small amplitude oscillation about its steady state. Find the period of oscillation. 1) A mass m on a massless string of length 1 hangs from the ceiling of a train accelerating with constant acceleration 9/8. a) Find the tension in the string and the angle that the string makes with the vertical if it is hanging in a steady state (i.e. not moving as seen by an observer in the train). b) Suppose the mass is set into small amplitude oscillation about its steady state.
