  1. A car is moving (very fast) at 75 m/s at an angle of 28°. Resolve the vector into its x and y components.
  2. One vector is 42.0 m long, at an angle of 25.0°. A second vector is 64.0 m long, at an angle of 35°. Find the resultant vector.
  3. What are the two different ways to multiply vectors?
  4. Vector A is pointed north; vector B is pointed east. What direction is the product of A cross B?
  5. You're walking across the deck of a boat. Your velocity with respect to the boat is 2.5 m/s, 37° east of south. The velocity of the boat with respect to the shore is 3.5 m/s, 12° east of north. What is your velocity with respect to the shore?
  6. Travel 75.0 m, 55° west of north. Then travel 95.0 m, 35° north of east. What is your displacement?
  7. A car is driving at 15.0 m/s, 26.0° north of east. It accelerates at 1.90 m/s2 for 2.90 s, in the direction 18° south of east. What is its final velocity?
