    You need to show us your attempt at work before we can offer tutorial help. Start by putting the 1/2at^2 all on one side, then isolate t^2, then what?

    That's a general quadratic equation. You can either "complete the square" or use the quadratic formula to solve for t.

    Berkeman, did you miss the "ut"? Getting t2 by itself won't help.
