Math Problem Statement

can you draw the graph and solve this problem?

Vector V, is 6.6 units long and points along the negative x axis. Vector V is 8.5 units long and points at +45° to the positive x axis. (a) What are the x and y components of each vector? (b) Determine the sum V, + V2 (magnitude and angle).

Solution

The graph above shows the vectors V1\mathbf{V_1} and V2\mathbf{V_2}, along with their resultant vector VR\mathbf{V_R}.

Summary of the Problem:

  1. Vector Components:
    • V1\mathbf{V_1}:
      • V1x=6.6V_{1x} = -6.6 units
      • V1y=0V_{1y} = 0 units
    • V2\mathbf{V_2}:
      • V2x=6.01V_{2x} = 6.01 units
      • V2y=6.01V_{2y} = 6.01 units
  2. Resultant Vector VR\mathbf{V_R}:
    • Magnitude: 6.04 units
    • Angle: Approximately 84.7-84.7^\circ (measured counterclockwise from the positive x-axis).
