A bright light on the ground illuminates a wall 12 meters away. A man walks from the light straight toward the building at a speed of 1.1 m/s. The man is 2 meters tall. When the man is 4 meters from the building, how fast is the length of his shadow on the building decreasing? (Give your answer correct to two decimal places.)

\n" ); document.write( "Similar to the boat problem.
\n" ); document.write( "Get the length of the shadow in terms of his distance from the building, that's just geometry.
\n" ); document.write( "Differentiate wrt time, etc.
