Calculation path

Calculate the nonnegative final-speed branch without requiring elapsed time. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

v=sqrt(u^2+2a delta x)

What you provide

What you provide

  • Initial velocity expressed in m/s, using the same scenario as the other inputs
  • Constant acceleration expressed in m/s^2, using the same scenario as the other inputs
  • Signed displacement expressed in m, using the same scenario as the other inputs

What you receive

What you receive

  • Final speed in m/s from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Acceleration is constant; direction information must be assigned separately from this speed magnitude.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
