- answer d,e,f partThe convention is to choose the direction of +z so that ?Xj=kwhich automatically means that IXi=-k. is called a right handed coordinate system. This allows one to write the cross product using components as This shown below. A=Azi+Ayj; B=Bzi+Byj_ The cross product in terms of the components is j and Assume two vectors therefore: ÄxB=A,B,(ixj)+4, B.(jxi)=(A, B,-A,B,.)k Use this formula for the cross product to determine the torque due to a force (7 î + 9 ĵ) newtons and applied at displacement (0.8 î + 1.2 ĵ) m from the axis of rotation. What is the z-component of the torque in newton-meters? Be careful, remember it matters which vector comes first.Let vector a = <-1,4,0> and vector b = <4,-4,1>. The the cross product of vector a and b.
- find a and bPlease answer b and c. I already answered a.E N Radar "dish" A radar station detects an airplane approaching directly from the east. At first observation, the range to the plane is 384.0 m at 41.0 ° above the horizon. The plane is tracked for another 124.0 ° in the vertical east-west plane, the range at final contact being 795.0 m. What is the magnitude of the displacement of the plane (in meters) during the period of observation?
- Let vector A point from the origin into the second quadrant of the xy plane and vector B point from the origin into the fourth quadrant. The vector B −A must be in which quadrant?write the force vectoradd the given vectors by the component method , by completing the table below. What is the angle of the resultant vector with respect to the xaxis?A = 6.0 N at 135°, B = 3.0 N at 225°, C = 8.7 N at 350
