text: Below is an context that describes a sql query, paired with an question that provides further information. Write an answer that appropriately completes the request.  # noqa: E501
  ### Context:
  CREATE TABLE table_15314901_1 (coordinate_velocity_v_dx_dt_in_units_of_c VARCHAR, condition_parameter VARCHAR)
  ### Question:
  If the the condition/parameter is rapidity of 2 hyperbolic radians, what is the coordinate velocity v dx/dt in units of c?
  ### Answer:
  SELECT coordinate_velocity_v_dx_dt_in_units_of_c FROM table_15314901_1 WHERE condition_parameter = "Rapidity of 2 hyperbolic radians"
