Question

Find the magnitude o

42

Find the vector's magnitude and direction. theta = 66.8 degree below + x-axis r rightarrow = (51.0 i +72.0 j) m 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 figure (Figure 1) (a) 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) Draw B rightarrow = -4i + 4j Draw the vector with its tail at the origin. Find the magnitude of B rightarrow. Express your answers using two significant figures. Find the direction of B rightarrow Express your answer using two significant figures.

Explanation / Answer

Magnitude=sqrt(51^2+72^2)

=88.23

Direction is tan^-1(72/51)

=54.68 degrees

Magnitude of B is sqrt(32)

Direction is tan^-1(-1)

=45 degrees
