You are a detective interviewing someone who says that (while sitting on a porch that you
know to be 600ft away) he saw the masked suspect commit the crime in broad daylight.
"How do you know it was the suspect?" you ask. "I clearly saw the 'MOM' that is tattooed
on his upper arm." "You're sure it was that particular tattoo and not some other tattoo?"
"Yes, I'm sure," The witness replies. The suspect's tattoo has letters that are 6cm tall. Is
the witness credible, or might he be framing the suspect? Justify your response and any
estimates you might make.

- A camera operator is filming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to his campsite. By watching debris flowing down the river, the operator estimates that the stream is flowing at 0.625 m/s0.625 m/s . In still water, the explorer can swim at 0.735 m/s0.735 m/s . At what angle, less than 90°, with respect to the shoreline should the operator advise him to swim so that he travels directly across the stream to his campfire The water is near freezing in temperature. Typically a human can only swim in such water for about 300 s300 s (or 5 min5 min ) before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 27.9 m27.9 m wide.arrow_forwardA bus is moving forward at 10 m/s.

Nature has adapted the bird to reach such a speed by placing baffles in its nose to prevent air from rushing in and slowing it down. Also, the bird's eyes adjust their focus faster than the eyes of any other creature, so the falcon can focus quickly on its prey. Assume that a peregrine falcon is moving horizontally at its top speed at a height of 100m above the ground when it brings its wings into its sides and begins to drop in free fall. How far will the bird fall vertically while traveling horizontally at a distance of 100m?arrow_forward
- A man in a boat is looking straight down at a fish in the water (n = 1.333) directly beneath him. The fish is looking straight up at the man. They are equidistant from the air/water interface. To the man, the fish appears to be 2.3 m beneath his eyes. To the fish, how far above its eyes does the man appear to be?arrow_forwardManuel is scuba diving near a school of fish at a depth of −9.5 feet relative to sea level.

- I need help with part a and b of this question! Thanks! For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 51.0 km due east and have it detected by a light sensor that is 129 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. ANS:____º Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. ANS:_____ marrow_forwardThe speed of light changes when it goes from ethyl alcohol (nea = 1.31) to carbon tetra- chloride (nct = 1.641).

- Two burning candles (a narrow and a wide, see the figure) are standing on a table at distance 20 cm from each other. Initially the candles are the same height. As the candles are burning, the shadow of the wider candle observed on the wall at distance 40 cm from it does not move at all. The narrow candle burns down in 1 hour.

The angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. Also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. Let's assume the rocket rises vertically and its speed is 600 ft/s when it has risen 3000 ft. (a) How fast is the distance from the television camera to the rocket changing at that moment? (b) If the television camera is always kept aimed at the rocket, how fast is the camera's angle of elevation changing at that same moment?
