I am having trouble getting going on this problem and I'm hoping someone can help get me started. I have no idea how to do solve this. Originally I thought about using Heisenberg's uncertainty principle and setting delta x = 1 m. Yet I don't see how the uncertainty in that direction is related to a perpendicular velocity that the car would be approaching in. Perhaps I just don't understand the concept fully, as I don't see why there is a minimum speed I must be going to be sure I won't hit the side. I will be grateful for any help. Cheers.
