The force on an object is F = 25 3 For the vector 3 = 27 43', find: (a) The component of F parallel to U: D (b) The component of F perpendicular to 3: D The work, W, done by force through displacement : O Consider the vectors Which pairs (if any) of these vectors are (a) Are perpendicular? (Enter none or a pair or list of pairs, e.g., if @ is perpendicular to b and , enter (a,b),(a,c).) (b) Are parallel? (Enter none or a pair or list of pairs, e.g., if @ is parallel to b and , enter (a,b),(a,c).) (c) Have an angles less than 11'/ 2 between them? [ (Enter none or a pair or list of pairs, e.g., if @ is at an angle less than pi/2 from b and , enter (a,b),(a,c).) (d) Have an angle of more than 1r/2 between them? (Enter none or a pair or list of pairs, e.g., if d is at an angle greater than pi/2 from b and , enter (a,b),(a,c).)
