Which variables can be negative?
Velocities and acceleration can be positive or negative depending on direction; time is taken as ≥ 0.
Why are there two possible solutions?
Quadratic equations (e.g., s = u t + ½ a t²) can produce two times. The tool reports the non-negative solution; if both are valid you’ll see a note in steps.
What about variable acceleration?
These equations assume constant acceleration. For variable a(t), use calculus or numerical integration.
