Algebra.Com's Answer #111884 by oscargut(2103)![]() ![]() You can put this solution on YOUR website! d=distance \n" ); document.write( "t=time \n" ); document.write( "K=constant of proportion \n" ); document.write( "the distance of a falling object is directly proportionae to the square of the time it falls before hitting ground \n" ); document.write( "then d=Kt^2 \n" ); document.write( "the object fell 144 ft in 3 seconds \n" ); document.write( "then 144=K(3)^2 \n" ); document.write( "then 144=9K \n" ); document.write( "then K=16 \n" ); document.write( "then equation is d=16t^2\r \n" ); document.write( "\n" ); document.write( "so if t =4 d=16(4)^2=16^2=256 \n" ); document.write( "Answer: it falls 256 ft after 4 seconds \n" ); document.write( " \n" ); document.write( " |
