Why does this not work? Projectile Motion problem for Dynamics Class

[QUOTE="kuruman, post: 6847951, member: 192687"] Your approach is correct, however your expression -0.04x[SUP]2[/SUP]= 0.5774x -0.003354x[SUP]2[/SUP] troubles me because its non-zero solution is negative and that can't be. Probably you made a mistake somewhere in your calculation of all these numbers. Try solving it using symbols all the way to the end. Then substitute the numbers at the very end. A symbolic representation of the answer would be easier to troubleshoot. Start by writing ##t=\dfrac{x}{v_0\cos(30^o)}## and replace that in ##y=v_0\sin(30^o) t-\frac{1}{2}gt^2## for starters.
