Please help me solve this problem. \"Three seconds after release, the height of an object is (1/2)(-32)(3^2) feet below the point of release. What is this height?
\n" ); document.write( ":
\n" ); document.write( "This is the equation for falling objects usually written\"
\n" ); document.write( "h = -16t^2
\n" ); document.write( "Where t = time in seconds and h is falling distance in feet
\n" ); document.write( ":
\n" ); document.write( "In your problem
\n" ); document.write( "h = -16(3^2)
\n" ); document.write( "h = -16 * 9 = -144 ft after 3 seconds, negative because it is falling \n" ); document.write( "

\n" );
