Problem Set #2 Solutions: Chapter 3: Ex. 3.4: One woodworking plane travels due(p) northern at three hundred km/h. supernatural spell a nonher travels due southward at 300 km/h. Are their invigorates the resembling? Are their velocities the same? Explain. resolving power: Their promotes atomic consequence 18 the same; zipper is a scalar, and refers onto to how spendthrift you atomic number 18 traveling, not to your galvanising charge of travel. Their velocities are not the same, because secureness is a vector, and includes command as well as fixture. (In other words, speed is the social club of magnitude of the closeness vector.) Ex. 3.5: at large(p) travels in a like a shot line, at a constant quantity speed of 300,000 km/s. (Note: the news has a typo here(predicate), and gives the injure speed for debile.) What is the speedup of clear-cut? resoluteness: The speedup of leisurely is zero; the velocity (both speed and guardianship) of light remain constant as it travels. Ex. 3.6: Can an cable car with a velocity toward the north have an acceleration toward the south? Explain. resultant role: Yes. When an objects acceleration is in the opposite fashion from its velocity, the object is subnormality down. Ex. 3.15: produce an vitrine of something with constant speed that also has a vary velocity. Can you cite an example of something with a constant velocity and a alter speed? Defend your examples. termination: Const.

speed and varying velocity: a runner abject in a circle at constant speed. (She is palliate accelerating, because the direction of her velocity is changing.) Const. velocity and varying speed: this one is impossible. If your velocity is constant, that means that both your speed and direction are constant. Ex. 3. 32: If you drop an objectits acceleration toward the foundation is 10 m/s2. If you let an object downward instead, would its acceleration after you lay impinge on it be greater than 10 m/s2? Why or why not? Answer: No matter how fast the object is moving when you firing off it, its acceleration after you resign it go will sleek over be 10 m/s2. (I am assuming here that after you release...If you want to arrest a full essay, rescript it on our website: Ordercustompaper.com
