Algebra.Com's Answer #795638 by htmentor(1343) You can put this solution on YOUR website! Combining the formulae v2^2 = v1^2 + 2ad and v2 = v1 + at, with v2=0, we have: \n" ); document.write( "v1 = sqrt(2ad), v1 = at -> t = sqrt(2d/a) \n" ); document.write( "Putting in d = 150 m and a = 16 m/s^2, we get t = sqrt(300/16) = 4.33 s \n" ); document.write( " |
