The two vectors a with arrow and b with arrow in the figure below have equal magnitudes of 11.7 m and their angles are θ1 = 30° and θ2 = 106°.
(a) Find the x and y components of their vector sum r with arrow. (Express your answer in vector form.)
(b) Find the magnitude of r with arrow.
(c) Find the angle r with arrow makes with the positive x axis

Best ResponseYou've already chosen the best response.0Vector form is i and j, i represent x direction j represent y direction. like 5i+6j is 5 coordinates to the right and 6 to the north. 5i6j would be 5 coordinate to the left and 6 to the south.

Best ResponseYou've already chosen the best response.0Angle 1 and 3 are corresponding angles so they are the same. Subtract 180 degrees from the (angles of 2 and 3) to get angle 5.

Best ResponseYou've already chosen the best response.0cos30=x/11.7 so 11.7cos30=x You would get the x component for vector A sin30=y/11.7 so 11.7sin30=y You would get the y component for Vector B

Best ResponseYou've already chosen the best response.0Now try to get the x and y component for vector B. After you get both, you would add the x component of vector A and B together to get the displacement or resultant x component. Then do the same to get the resultant vectors y component.

Best ResponseYou've already chosen the best response.0For vector A we can definitely do what you said, but not for vector B because it has a 106 degree angle.

Best ResponseYou've already chosen the best response.0You were right on that. And I said your 74 degrees on angle 5 is wrong. Look at my drawings again.

Best ResponseYou've already chosen the best response.0But how did you know angle 1 is 30 degrees? Please reread. _

Best ResponseYou've already chosen the best response.0Whenever there is an angle that is not 0 or 90 or 180 degrees, I do not just assume the angle number. It has to be given by the information.

Best ResponseYou've already chosen the best response.0I cant just guess that angle 1 is 30 degrees without info.

Ac3

Best ResponseYou've already chosen the best response.0angle 1 is 30 that's a given.

Best ResponseYou've already chosen the best response.0Yes, so you should have no trouble knowing what angle 2 is. Always read your question and information carefully. It helps a lot in physics.

Best ResponseYou've already chosen the best response.0If I dont know what angle 2, I would not figure out how to do this.
