- Calculating Displacement- 1. A woman walking her dog travels 200 m north, then 400 m west, then 500 m south. (a). What was the total distance she travelled? (b) What was the magnitude of her displacement for the entire trip?A furlong is a distance of 220 yards. A fortnight is a time period of 2 weeks. A race horse is running at a speed of 2.3 yards per second. What is his speed in furlongs per fortnight?.5What is 71 mph in terms of m/s? 1.000 mile = 1609 m. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
- How does something that operates in milliseconds compare to something that operates in nanoseconds? What is the difference in terms of the order of magnitude?For a short time, the speed v of a car, in m / s, is given by v = at2 + bt3, where t is the time in seconds. The units of a and b are, respectively, a) m/s^2; m/s^3 b) m/s^4; m/s^5 c) s^3/m; s^4/m d) m.s^2; m.s^4 e) m/s^3; m/s^4Tom Cogwagee Longboat, of the Six Nations of the Grand River, is one of Ontario's best known distance runners.
