I would like help with part d) please as I am not sure how to answer
(a) Vector Ē has magnitude 17.0 cm and is directed 27.0° counterclockwise from the +x axis. Express it in unit-vector notation. (b) Vector F has magnitude 17.0 cm and is directed 27.0° counterclockwise from the +y axis. Express it in unit-vector notation. (c) Vector Ğ has magnitude 17.0 cm and is directed 27.0° clockwise from the -y axis. Express it 3. in unit-vector notation. = d) Find Ē+F+G in unit vector notation 17cos27î + 17sin27ĵ = 15.15î + 7.72) %3D Here both components are positive as E lies in first quadrant b}F = –17sin27î + 17cos27ĵ = –7.72î + 15.15) %3D Here the F lies in second quadrant so y-component is positive and x-component is negative. 9G = -17sin27î – 17cos27ĵ = –7.72î – 15.15) %3D Here the G lies in third quadrant so both x-component and y-component are negative.
