Use this final velocity calculator without time to calculate the upward velocity of any object. I have noticed many people use a = [Vf2 - Vi2] / [2d] for a very similar question, but I am unsure where that formula comes from, as I thought acceleration was a difference of velocity/time, not a difference of velocity/2*distance. So to find the stopping time you have to solve $$ 32 - 0.7 t = 0 \\ t = 320/7 \approx 45.71 $$ Now you need to compute the number of revolutions, and here a trick is to note that the average angular velocity will be exactly half the initial angular velocity, since it is slowing with constant deceleration. I know that velocity V = acceleration (a) X time (t). This section assumes you have enough background in calculus to be familiar with integration. Then it asks me to find acceleration and velocity at the maximum height. This is done by the formula $d(t)=\frac{9.81t^2}{2}$ (the reason is that you want $\int \limits_{0}^t 9.81xdx$ ). velocity= \dfrac {\bigtriangleup distance} {time} velocity = time distance.
