If you're on the road in car 2 going 20 m/s and car 1 is going 25 m/s in the dafne direction it would look as if it was passing you at 5 m/s west. This is because 25 m/s - 20 m/s = 5 m/s

Answer:
A. 5.600 m
B. 5.800 s
C. 0.966 m/s
D. 0.315 m
Explanation:
A. The wavelength is the distance between 2 crests, which is 5.600 m
B. Period of the wave is the time for the wave to complete 1 circle (highest point to next highest point). Since it takes 2.9s to travel from highest point to lowest point, it would take another 2.9 to travel from lowest point to the next highest point. So the total time is 2.9 + 2.9 = 5.8 s,
C. The wavespeed is wavelength over unit of time:
5.6 / 5.8 = 0.966 m/s
D. The amplitude would be half the length of highest point to lowest point, which is 0.63 / 2 = 0.315 m
