A student applies the work-energy theorem to a system and derives the final speed of a block after it slides a distance dd down a rough incline of angle θ\theta, starting from rest, as: v=2gd(sin⁡θ+μkcos⁡θ)v = \sqrt{2gd(\sin\theta + \mu_k\cos\theta)} The student performs a unit check and confirms the expression has units of m/s. Which of the following best identifies whether this answer should be accepted or rejected, and why?
