Question 1 A vector in Cartesian coordinates can be represented as a list of three values giving the x, y, and z components of the vector, as shown in the example below: # = (3, 7, –5). where in this example the x component of the vector is 3, the y component of the vector is 7, and the z component of the vector is -5. We can also represent a vector using the unit vectors i, 3, and &. This is the notation we will use the most in this class because we can do algebra and calculus on our vector just by treating î. §. and k as constants. Which of the following is the correct representation of 7 = (3, 7, –5) using unit vector notation? OF = (31, 73, –3k) O7- 31 + 73 – 5Å OF (3i)(73)(-5k) OF = 31, 73, –5k; Question 2 The vector pictured below lies in the xy plane. It has a length of r= 34.4 cm and it makes an angle of 0 - 74.5 degrees with respect to the x axis. y What is the x component of the vector? Give your answer in cm with a precision of 0.1 cm.

PHYSICS VECTORS

Question 1
A vector in Cartesian coordinates can be represented as a list of three values giving the x, y, and z
components of the vector, as shown in the example below:
7 = (3,7, –5).
where in this example the x component of the vector is 3, the y component of the vector is 7, and
the z component of the vector is -5.
We can also represent a vector using the unit vectors î, j, and k. This is the notation we will use
the most in this class because we can do algebra and calculus on our vector just by treating î. j.
and & as constants.
Which of the following is the correct representation of 7 = (3, 7, –5) using unit vector notation?
OF = (31, 7), -5k)
O7 = 3i + 73 – 5k
O7 = (3i)(73)(-5k)
O7 = 31, 73, -5k;
Question 2
The vector pictured below lies in the xy plane. It has a length of r = 34.4 cm and it makes an angle of
0 - 74.5 degrees with respect to the x axis.
y
What is the x component of the vector?
Give your answer in cm with a precision of 0.1 cm.
