Final velocity during braking
During a sports biomechanics lab, an object has initial velocity \(24\,\text{m s}^{-1}\) and acceleration \(-2.5\,\text{m s}^{-2}\) for \(7\,\text{s}\). Calculate the final velocity. Enter the numerical result and choose the interpretation that matches the physics meaning.
