    Motion in One Dimension
    An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads. The Photograph is made when the angle of elevation of the sun is 32 degrees. By comparing the shadow cast by the building to objects of known size in the photograph, analysts determine that the shadow is 80 ft long. How tall is the building in feet?

    I suggest you draw a sketch of the sun casting a shadow from a vertical object when the sun is at 32 degrees above the horizon (the horizontal), and apply what you know about trig functions to determine the relationship between the height of the object and the length of its shadow.
