Answer 1

What type of engineering are you studying if you have so much trouble with this problem?
Put everything on one side, and you will recognize (hopefully) that you have a quadratic with t as the variable, 1/2 a, u and -s as coefficients of the three terms respectively. You do the quadratic equation solution thing, making sure you reject a negative number as a solution.
