Algebra.Com's Answer #335571 by chessace(471)![]() ![]() You can put this solution on YOUR website! If \"how long\" means Time, just divide (-)V / A. \n" ); document.write( "Keep units to make sure: \n" ); document.write( "(-20.1 m/s) / (-0.0500 m/(s^2)) \n" ); document.write( "= (20.1/0.0500) sec \n" ); document.write( "= 402 sec. = 6 Min 42 Sec. \n" ); document.write( " \n" ); document.write( " |
