Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.

In case you want them, here are the answers to tomorrow night’s problems.

b. 20 m/s
43. a. 10.1 m/s at 8.53° east of north
b. 48.8 m
44. a. 14.1° north of west
b. 199 km/h
45. 7.5 min
46. a. 23.2° upstream from straight across
b. 8.72 m/s across the river
50. a. 22.2 s
b. 2.00 × 102 s
