Determine the magnitude of the sum of the three vectors V, = 6.0 1 - 9.0 j, V2 - i + j. and V3 - -2.0 1 +5.0 3. You are given a vector in the ary plane that has a magnitude of 80.0 units and a y component of -50.0 units. Express your answer using two significant figures. 5.8 Part A Previous Answers What are the two possibilities for its r component? Correct Enter your answers numerically separated by a comma. X1, 12 = 62.4,-62.4 units Part B Previous Answers Determine the angle (in degrees) of the sum of the three vectors V, - 6.0 i - 9.0 j, V2 - i + j. and V3 - -2.0 i +5.0 3. Correct Express your answer using two significant figures. Part B AED FOE ? 150 Assuming the z component is known to be positive, specify the vector V which, if you add it to the original one, would give a resultant vector that is 72.0 units long and points entirely in the -z direction.
