Question 11 11. Which of the following is NOT an example of a vector's direction?

Question 12 12. If an object is moving at 4 m/s in the x-direction, and 2 m/s in the y-direction, what is the velocity of the object written in terms of standard basis vectors?

Question 13 13. Which of the following vectors is NOT in component form?

Question 14 14. You're pushing a shopping cart with a 20 N force downwards and a 50 N force forwards. What is the overall magnitude of the force you're applying?

Question 15 15. A truck is moving at 5 m/s north and 3 m/s west, while a person INSIDE the truck runs in a particular direction at a particular speed. The total velocity of the person (the combination of the velocity of the truck and the velocity of the person) is 6 m/s north and 1 m/s west. How fast must the person be moving inside the truck?

Question 16 16. If you shoot something up at a high angle, how will the x and y components compare?

Question 17 17. How do you add vectors geometrically?

Question 18 18. Why do we use standard basis vectors in physics?

Question 19 19. How would you write 50 newtons east, and 70 newtons south in component form? (Use north to south as the y-axis, and east to west as the x-axis, like in the lesson.)

Question 20 20. If vector 1 has a magnitude of 3, and a direction of 30 degrees below the negative x-axis, and vector 2 has a magnitude of 4, and a direction of 80 degrees below the negative x-axis, what is vector 1 minus vector 2? (Please complete this question geometrically using paper, a pencil and a ruler.)
