3. The initial point of a vector is (-3, 1) and the terminal point is (2, -1). Sketch the vector on the grid to the right. Then find its 2 magnitude to the nearest hundredth. Show your work. -3 -2 2 3 Get the Gizmo ready: Activity B: Drag the initial point of both vectors to the origin. Vector sums . Drag the terminal point of a to (0, 5) and the terminal point of b to (2, 0). 1. Vector a represents the velocity (speed) and direction of a boat crossing a river.why Vector b represents the velocity and direction of a strong west-to-east current the + boat encounters. 5 mph A. How do you think the current will affect the boat? a 2 mph Sketch c to the right to show where you think the boat will go. B. Turn on Show resultant. Vector c is the resultant, or sum, of vectors a and b. In this case, c shows the resulting velocity and direction of the boat. What are the components of c? 2. Turn off Show resultant. With the initial points at the y origin, change a to and b to . Sketch these vectors on the grid to the right. A. What do you expect the components of the resultant to be? X B. Turn on Show resultant, and sketch the 2 3 6 resultant in your diagram. What are the --1 components of the resultant? -2 C. In general, how can you use the components of a and b to find the components of c
