Find a unit vector in R2 which is perpendicular to = -31+3j. unit vector: -1+?j The force on an object is F=27+87. For the vector d = 7+47, find: (a) The component of F parallel to a. Use the drop-down menu to indicate if the second term is negative and enter a positive number in the answer area. In the case of a zero coefficient, select "+" and enter 0. Enter a numeric value in each answer area. F parallel 3.77 (b) The component of F perpendicular to d. 15.11 7 Use the drop-down menu to indicate if the second term is negative and enter a positive number in the answer area. In the case of a zero coefficient, select "+" and enter O. Enter a numeric value in each answer area. F perp (c) The work, W, done by force F through displacement. 7 W = 34 Use = 97+107-7k and w = 7-7+2k to calculate the following. W =
