A automotive test driver travels due north in a prototype hybrid vehicle at 30 mi/h for 2 hours. She then reverses her direction and travels due south at 60 mi/h for 1 hour.
What is the average velocity of the vehicle?
40 mi/h, south
45 mi/h, north
45 mi/h, south...
vector A has a magnitude of 81 units and points due west, while vector B has the same magnitude and points due south. Find the magnitude and direction of (a) A + B and (b) A - B . Specify the directions relative to due west.
(a) Magnitude and direction of A + B = and o
(b) Magnitude and...
