Ablue car of length 4.51 m is moving north on a roadway that intersects another perpendicular roadway. the width of the intersection from near edge to far edge is 29.5 m. the blue car has a constant acceleration of magnitude 2.20 m/s2 directed south. the time interval required for the nose of the blue car to move from the near (south) edge of the intersection to the north edge of the intersection is 3.20 s
(a) a red car is at rest on the perpendicular intersecting roadway. as the nose of the blue car enters the intersection, the red car starts from rest and accelerates east at 5.50 m/s2. what is the minimum distance from the near (west) edge of the intersection at which the nose of the red car can begin its motion if it is to enter the intersection after the blue car has entirely left the intersection?
m
(b) if the red car begins its motion at the position given by the answer to part (a), with what speed does it enter the intersection?

You have been consulted by the mobile phone company hookup about a new augmented reality product called “brows”. they want to develop an alternative to google glasses, which, you recall, is a proposed new product which plans to superimpose a whole range of wireless google services over the user’s ordinary vision of the world. these appear in little circles and ovals, and let you phone people, take photographs, navigate across cities and inside buildings, find shops and update your social media. brows would do this too, but not be limited to special google services. the user would wear a small cylinder-shaped device designed to fit on top of their existing eyewear (glasses or sunglasses). it would project a reversed image onto the inside of the lenses, the reflection of which would be in focus for the user. instead of voice control, the user would control the device by eye and neck movements, which the device would track. the device would connect via bluetooth to the user’s phone, which would supply most of the computing power and wireless connectivity. hookup also wants to know what existing services would be most in demand, and which would not work well with brows. using your knowledge of augmented reality, wearable technology and interface design, is the project feasible? if not, why not? if feasible, how could the product need to be modified for a better experience?
