Explanation / Answer

Here are the step: Part A: it's just 1 cm find it on wikipedia there's no work to be done Part B: use the equation x = (1/2)a(t^2) + Vo*t + Xo Vo and Xo equal zero so it reduces to x = (1/2)a(t^2) Plug in your numbers and solve to get acceleration Part C: V = at Just plug in your number to solve for velocity
