Suppose that the speed of light in a vacuum ( cc), instead of being a whopping 3×108m/s3×108m/s, was a rather sluggish 40.0mph40.0mph. How would that affect everyday life? Throughout this problem we are going to assume that c=40.0mphc=40.0mph and that time dilation is in full effect. Let's start by assuming that it is fairly easy to accelerate to speeds close to 40.0mph40.0mph. We will also ignore gravity throughout this problem. Otherwise, the earth (with an escape velocity of 11km/s11km/s) would have turned into a black hole long ago. Part B The restaurant the student likes to go to doesn't have any clocks. As a result, the only way that the student can keep track of the time so as not to be late is to keep an eye on her wristwatch. According to the student's watch, how much time does she actually have for the entire lunch break (travel, serve, and eat) if she wants to go to the furthest restaurant?
