To believe that patriotism will not flourish if patriotic ceremonies are voluntary and spontaneous instead of a compulsory routine is to make an unflattering estimate of the appeal of our institutions to free minds. Struggles to coerce uniformity of sentiment in support of some end thought essential to their time and country have been waged by many good as well as by evil men. Such attempts to compel coherence by forcing a flag salute or pledge of allegiance are ultimately futile.

An object falls with an acceleration of a= -9.81 m/s^2. A function relating the height from which the object falls, the initial velocity of the object, and the time the object spends in the air is frequently used in physics.
Lucy and Kim determine the height of a building by dropping a brick from its roof. The initial velocity is 0m/s because lucy simply let go of the brick. Kim times the fall of the brick to be 3.5 seconds. What is the height of the building?
Determine the amount of time the brick is in the air if Lucy throws the brick downward with an initial velocity of -5m/s. Round to the nearest hundreth of a second.
