Let’s add the following three vectors. Sketch the vectors. Vector A: 30.0m/s at 36.9o^ West of South Vector B: 60.0m/s at 66.4o^ North of West Vector C: 90.0m/s at 45.5o^ East of North 1st step: find the x-component of A:_____________________ find the x-component of B:______________________ find the x-component of C:__________________________ 2nd step: find the y-component of A:______________________ find the y-component of B:_______________________ find the y-component of C:________________________ 3 rd step: Sum the x-components:______________________ Sum the y-components:______________________ 4 th^ step: Use Pythagorean Theorem to find magnitude of resultant Magnitude:__________________________________________

5 th step: Calculate direction of resultant vector using Angle:______________________________________________

The length of vector A is 250 units and the length of vector B is

350 units. If these two vectors are added together, what is the

maximum possible length of their sum? Please illustrate your

response with a drawing.

600 units the vectors must be parallel.

What is the minimum possible length of their sum? Please

illustrate your response with a drawing.

100 units; the vectors must be in opposite directions.
