Thanks gneill! I think I got it now, I used the formula (-cos21)(0.2)s=(Sin21)s-((9^2)/(2g)) = 7.573m Hope its right, thanks 4 all ur help guy! xx

Thanks Tiny-tim! But since I don't have mass, height or force, how am I supposed to calculate work or mechanical energy? Is there too many unknowns or am I just not reading the question properly? I know this make me look stupid but I just can't get my head around it! Thanks very much for your...

A package is projected up a an incline of 21 degrees with respect to the horizontal, with an initial velocity of 9 m/s. The coefficient of friction between the package and the slope is 0.2. Determine the maximum distance the package will slide up the incline. Sorry guys I'm just really stuck...
