Find the magnitude
3
Find the vector's magnitude and direction. A rightarrow = 3.00 i - 7.00 j Let B rightarrow = (9.0m. 55 degree counterclockwise from the vertical). Find the x- and y-components of B rightarrow in the coordinate system shown in the fioure Express your answers using two significant figures. Enter your answers numerically separated by a comma. Find the x- and y-components of B rightarrow in the coordinate system shown in the figure (b). Express your answers using two significant figures. Enter your answers numerically separated by a comma. Let E rightarrow = 3i + 1j and F rightarrow = 2i - 3 j. Find the magnitude of E rightarrow Find the magnitude of F rightarrow. Find the magnitude of E rightarrow + f rightarrow. Find the magnitude of - E rightarrow - 2 F rightarrow.Explanation / Answer
Magnitude of A=sqrt(5^2+7^2)
=sqrt(74)
Direction is tan^-1(-7/3)
=-66.80 degrees
Magnitude of E is sqrt(10)
Magnitude of F is sqrt(13)
Magnitude of E+F is sqrt(29)
Magnitude of E-F is sqrt(17)
