B) A car is moving along a straight road while slowing down.
C) A car is moving along a straight road while speeding up.
D) A hockey puck slides along a smooth (i. e., frictionless) icy surface.
E) A hockey puck slides along a rough concrete surface.
F) A cockroach is speeding up from rest.
G) A rock is thrown horizontally; air resistance is negligible.
H) A rock is thrown horizontally; air resistance is substantial.
I) A rock is dropped vertically; air resistance is negligible.
J) A rock is dropped vertically; air resistance is substantial.
Which of these situations describe the motion shown in the motion diagram at point C?
Type the letters corresponding to all the right answers. Do not use commas. For instance, if you think that only situations c and d are correct, type cd.

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?
