Lesson 2: Problem Set 1 (40 Points)
Set has four problems with multiple parts. Each problem is worth 10 points
total. You are required to SHOW ALL YOUR WORK and give complete explanations
Don’t hesitate to use words to explain what you are doing
along the way. Circle or highlight the final answers in yellow. Be sure to
include units where appropriate. It is recommended that you print the problem
set worksheet and work the problems manually. You may scan the completed
worksheet or take a picture of the worksheet. Insert the picture or scan into a
Word document for submission. Upload the
final document to submit.
The four questions below constitute the Lesson 2 Problem Set
and will be graded.
Answer the questions below:

Vector R has a magnitude of 10 units and is orientated at an
angle of 30o above the x-axis.
Find the x-component
of vector R.
Find the y-component
of vector R.
If the x-component
of vector R is doubled and y-component remains the same, what is the resulting
magnitude and direction of the new vector Q?
