Questions and Answers

- 1.Brian is at school and wants to walk home. How far and in what direction should he travel? A negative value means the negative x-direction, and a positive value means the positive x-direction.
- 2.How far is he from school? (what is his distance from school?)
- 3.Input the displacement vector from the school to his friend's house.
- 4.Enter the numbers for the displacement vector from his friend's house to his home.
- 5.Now why are these numbers negative? Choose the best reason why:
- A.
He was walking backwards.

- B.
His endpoint was in the negative x-direction AND in the negative y-direction, compared to his starting point.

- C.
It means he was feeling bad during the walk home.

- 6.Displacement vector for house to school:
- 7.Displacement vector for school to friend's house:
- 8.Displacement vector for park to friend's house
- 9.Displacement vector for house to park
- 10.Brian's total displacement vector starts from his initial location (his house 2,1) and ends at his final location (his friends house 16,8). In other words, it starts at the base of the first vector and ends at the tail of the last vector. What are the values of this total displacement vector?
- 11.For Brian's trip from his house to the fountain, why is the ŷ vector larger than the x̂ vector?
- A.
He walked further in the y direction than the x.

- B.
The y direction was "up" so its a large number.

- C.
He walked faster in the y direction than he did the x direction.

- 12.For Brian's trip from the fountain to his friend's house, why is the ŷ vector negative?
- A.
Going to school is negative.

- B.
They walked in the negative y direction.

- C.
They walked slower in the y direction.

- 13.Brian walks from his house (located at A) to the park (located at B), and then to his friend's house (located at C). Let's find how to calculate the x segment of the total displacement vector. What is the displacement x component of vector for A to B
- 14.Brian walks from his house (located at A) to the park (located at B), and then to his friend's house (located at C). Let's find how to calculate the x segment of the total displacement vector. What is the x componenet displacement vector for B to C
- 15.Brian walks from his house (located at A) to the park (located at B), and then to his friend's house (located at C). Let's find how to calculate the x segment of the total displacement vector. What is x component of the total (A to C) displacement vector
- 16.Brian walks from his house (located at A) to the park (located at B), and then to his friend's house (located at C). Let's find how to calculate the y segment of the total displacement vector. What is the displacement y component of vector for A to B
- 17.Brian walks from his house (located at A) to the park (located at B), and then to his friend's house (located at C). Let's find how to calculate the y segment of the total displacement vector. What is the displacement y component of vector for B to C
- 18.Brian walks from his house (located at A) to the park (located at B), and then to his friend's house (located at C). Let's find how to calculate the y segment of the total displacement vector. What is the displacement y component of vector for A to C
