Algebra.Com's Answer #209235 by texttutoring(324)![]() ![]() You can put this solution on YOUR website! If D is directly proportional to the square of the time (t), then we can set up this equation:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Where a is the proportionality constant. To solve for a, just use the information they gave you, with D=2304 and t=8 seconds.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now use this constant with the distance of D=900 to find the corresponding time:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The time it takes to fall 900 feet is 5 seconds. \n" ); document.write( " |
