- ##s##=##ut##+##\frac {1}{2}####at^2##

Now this is a textbook example with solution.

I understand working to solution...my only reservation is on how they used acceleration. The cyclist, i understand was traveling at a constant acceleration of ##2## ##m/s^2## before reaching the top part of the slope.

Now, if he is descending, which outrightly is deceleration or rather retardation, then are we assuming that he is traveling at the same constant rate of acceleration?

ok, i think i get it now...When going down the slope we are now going to have our initial velocity being ##u=1.5####m/s##...

i had to imagine/visualize a cyclist in motion going up a slope then change of direction to negative slope (still in motion)...then it is clear that the initial velocity will be ##1.5##m/s^2##...cheers guys...
