Question
1. Consider Wonder Woman flying through the air. Anyway, if v wg velocity of Wonder Woman relative to ground v wa velocity of Wonder Woman
1. Consider Wonder Woman flying through the air. Anyway, if vwg velocity of Wonder Woman relative to ground vwa velocity of Wonder Woman relative to air vag wind velocity (velocity of air relative to ground)
Which of the following equations is correct?
a. vwa= vwg + vag
b. vwa = vwg - vag
c. vag = vwg + vwa
d. vwg = vwa vag
2. Wonder Woman is flying at 250 m/s at a 4 angle east of north relative to the air. The wind is blowing at 55 m/s due west relative to the ground. What is the magnitude of the velocity of WW relative to the ground?
a. 193 m/s
b. 223 m/s
c. 239 m/s
d. 249 m/s
e. 252 m/s
3. For Wonder Woman in the previous problem (#13), what is the angle of her velocity relative to the ground, as measured from the north axis?
a. 6.2
b. 8.6
c. 13.1
d. 81.4
e. 83.8
4. Suppose instead the answer to the previous problems (#13 and #14) were that Wonder Woman's velocity relative to the ground had a magnitude of 220 m/s and an angle of 2 east of north. After one minute, how far will she travel in the east-west direction?
a. 65 m
b. 105 m
c. 220 m
d. 461 m
e. 1.32 km
