1. Do Now:
1. Remember Mailman Rich? He walked 22 km North, then 47 km South of East at 60o. EXPLAIN how we calculated the resultant mathematically?
60o
22 km
47 km
Resultant

2. Aim: How do we solve 2D vector Problems?
HW: Vector component WS

3. Remember!
Resultant = Sum of two or more vectors! For Mailman Rich… D1 + D2 = Resultant + =

4. Solving 2D Vector Questions
If vectors form a right triangle: Use Pythagorean Theorem and SOHCAHTOA
If Vectors given in multiple directions (angled) or more than two are given:
Sketch a diagram
Separate vectors
Break each vector into x & y components
Add similar components
Using combined x and y components to make a new right triangle and solve for resultant using Pythagorean theorem and SOHCAHTOA.

5. White Board Activity
Solve the following Vectors for their x & y components.

6. Practice
Joe pulls a box North East at 45o with a force of 10 N and Mary pushes the box Southwest (200o) with a force of 15 Newtons. What is the Net force on the box?

7. Practice
Joe pulls a box North East at 45o with a force of 10 N and Mary pushes the box Southwest (200o) with a force of 15 Newtons. What is the Net force on the box?
10N
200o Southwest = 20o Southwest y2
45o x y x2
15N

8. Summary
1. How do we solve for the resultant if there are more than 2 vectors or vectors in more than one direction?
