Question

Given the following vectors: (not the same as above!) Ā= (30.ON , 20.0°),B = (50.0 N,195.0°), and C = (20.ON , 140.0°) where N is the unit of force in the SI system (N=Newton) Calculate the vector R = 1.5Ă – 0.8B + 1.2č by graphical addition. (scalar multiplication and vector addition/subtraction) Calculate the vector R = 1.5Ă – 0.8B + 1.2č by Cartesian components. Convert the Cartesian form of R to its Polar form Determine the vector –R. Express in both Cartesian and Polar form. Set up a circular object on Interactive Physics (IP). Turn off gravity. Apply four forces at the center of the object. The four forces are: -R, 1.5Ā, –0.8B, and 1.2ć. Measure the total force on your object. Given that an object accelerates if the total force on the object is nonzero, is your simulation consistent with this statement? Why or why not?
