Chapter 2, Problem 6PQ
In the traditional Hansel and Gretel fable, the children drop crumbs of bread on the ground to mark their path through the woods. Unfortunately, the crumbs are eaten by birds, and the children cannot find their way home. In this modern-day problem, the children use a device that releases a drop of food dye once per minute. As long as it does not rain, they can find their way home. As an extra bonus, they make a motion diagram as shown in Figure P2.6.
- a. Describe the motion of the children in words.
- b. Using the coordinate system in Figure P2.6, make a position-versus-time graph. Note any ambiguities you encounter.
- c. Is your position-versus-time graph consistent with your description in part (a)? Explain.

Moving sidewalks are installed every other 50 meters along the entire stretch of an airport walkway. These sidewalks move at a constant speed of 1 m/s. A lady passenger takes one of the sidewalks to go from one point to the next.
If the passenger decides to go back using the same sidewalk at 1 m/s, how long will it take to reach her point of origin?
On a particularly busy workday, I might need to drive back and forth between ASUN’s Newport and Jonesboro campuses, which are 38 miles apart. It takes me 48 min to make the drive from the Newport campus to the Jonesboro campus. On the return trip from Jonesboro to Newport, I decide to speed by maintaining an average speed that is 10 mi/hr faster than my average speed going from Newport to Jonesboro.

- I have an unusual question. I am getting confused with my graphs. I completed a few graphs and one in particular, a displacement-time graph was presented as displacement (cm) and time (s).

From t = 9 s to t = 15 s the object is at the same position. After that, it returns along the same track. The positions of the dots for t ≥ 16 s are offset for clarity. Which graph best represents the object’s velocity?arrow_forwardAs a city planner, you receive complaints from local residents about the safety of nearby roads and streets. One complaint concerns a stop sign at the corner of Pine Street and 1st Street. Residents complain that the speed limit in the area (89 km/h) is too high to allow vehicles to stop in time. Under normal conditions this is not a problem, but when fog rolls in visibility can reduce to only 47 meters. Because fog is a common occurrence in this region, you decide to investigate. The state highway department states that the effective coefficient of friction between a rolling wheel and asphalt ranges between 0.842 and 0.941, whereas the effective coefficient of friction between a skidding (locked) wheel and asphalt ranges between 0.550 and 0.754. Vehicles of all types travel on the road, from small cars with a mass of 531 kg to large trucks with a mass of 3463 kg. Considering that some drivers will brake properly when slowing down and others will skid to stop, calculate the minimum and…arrow_forward

Thinking it might be the Road Runner, he scampers up to speed and runs towards the sound to the East.
