Two students stretch a uniform rope of length L = 3.5 m and mass m = 0.85 kg between them. One of the students gives the rope a quick up-and-down shake and produces a transverse pulse that travels the length of the rope in time t1 = 1.3 s. Part (a) What is the tension in the rope, in newtons?

Part (b) A third student uses a slow-motion camera to observe the pulse and measures that it takes a time t2 = 0.15 s for the full width of the pulse to pass by her. She also carefully measures the height of pulse (from the equilibrium level of the rope to the pulse’s peak) to be h = 0.15 m. What is the pulse’s width, in meters?

Part (c) A point on the rope is marked with a red spot. As the pulse passes by, what is the spot’s average speed, in meters per second, during its transverse motion from equilibrium position to peak and back?

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?
