Still not sure which equation to use. Asked previously and feel the answer was not right. Stone thrown vertically upward with a speed of 24 m/s. How fast is it moving when it reaches a height of 20.6m. Previously when asked I said 13.0 m. The answer was wrong. So I am wondering if the equation is wrong.
