When you are driving you should be able to determine whether you can safely move your vehicle into a space located: All of the above; (To the front, side, and rear). By re-writing the first equation, we can calculate the speed at which the collision occurs: $$V_{f} = \sqrt{V_{0}^{2} - 2ad} = 8.2\mbox{ }metres\mbox{ }per\mbox{ }second$$. This makes the car deviate from the straight line in which it is travelling and go round the bend.
