4. Problem 4 For this problem, suppose we have two vectors v and W. We want to nd the value of the cross product v x w, but we do not know exactly what these vectors are. However, we do know the following bits of information: o The vectors v and w have lengths 5 and 4, respectively. a The two vectors both lie in the plane a: + y + 22 = 0. o The dot product of these two vectors is v - w = 10. (a) (Evaluated for mathematical work - accuracy and notational neatness) Find a possible correct answer for V X W. VXW= (b) (Evaluated for justication and written explanation) Is this the only possible correct answer based on the given information, or is there more than one? If the answer you found in part (a) is the only correct answer, explain why. Otherwise, explain how many possible answers there are. Explanation: (Use complete sentences)
