Figure 4-26 gives the path of a squirrel moving about on level ground, from point A (at time t = 0), to points B (at t = 5.00 min), C (at t = 10.0 min), and finally D (at t = 15.0 min). Consider the average velocities of the squirrel from point A to each of the other three points. Of them, what are the (a) magnitude and (b) angle of the one with the least magnitude and the ( c) magnitude and (d) angle of the one with the greatest magnitude? |
| Answer» SOLUTION :(a) 0.0083 m/s, (b) `0^(@)` (measured COUNTERCLOCKWISE from the +x axis), ( C) 0.11 m/s, (d) `297^(@)` (counterclockwise from +x) or `-63^(@)` (which is equivalent to MEASURING `63^(@)` CLOCKWISE from the +x axis). | |
