Okay, I have no clue what I am doing wrong. I've been following part a of this
http://www.webassign.net/latex2pdf/2a2176c1f300dcc09b8a130c84af8595.pdf
solution to help me with part a of this question I'm stuck on: If a rock is thrown upward on the planet Mars with a velocity of 18 m/s, its height (in meters) after t seconds is given by H = 18t − 1.86t^2. Find the velocity of the rock after two seconds. No matter what I do, it's still the wrong answer and it's becoming really frustrating considering that notes that my professor gave my class doesn't help with this at all.

Best ResponseYou've already chosen the best response.0I left because you weren't helping me at all with what you were suggesting and was adding to my frustration. And surjithayer, I knew I had to find v(2), that's the whole point of the question but I was struggling with trying to get the correct answer.

Best ResponseYou've already chosen the best response.0\[\frac{ dH }{ dt }=182*1.8t=183.6t\] when t=2 v=183.6*2=187.2=10.8 m/s

Best ResponseYou've already chosen the best response.0it is not 1.8 ,it is 1.86 2*1.86=3.72 when t=2 v=183.72*2=187.44=10.56m/s
