The problem is if a person on a creek bed throws a rock straight up at a speed of 64 feet per second. 1) when will the rock reach a maximum height? 2) when will the rock hit the water again?<BR>\n" );
document.write( "This is how I have satrted: I used the formula by putting 64 in the v spot and 0 in the s spot because I started at 0. It looks like this<BR>\n" );
document.write( "h=-16t^2 + 64t +0. I worked it out and got 2(1+-1) =t so my answer would be <BR>\n" );
document.write( "t=0 and t=4  If that is right then would the answer to #1 be half of that which is 2 seconds and the answer to #2 would be 4 seconds when it hits the water again. Am I on the right path or am I totally off? </SPAN>\n" );
