The unit vector is given by the following formula: a '= (a) / (lal) Where, a: vector a lal: Vector module a We are looking for the module: lal = root ((- 15) ^ 2 + (8) ^ 2) lal = 17 Same direction: a = -15i + 8j The unit vector is: a '= (1/17) * (- 15i + 8j) Opposite direction: a = 15i - 8j The unit vector is: a '= (1/17) * (15i - 8j) Answer: a unit vector that has the same direction as the vector a is: a '= (1/17) * (- 15i + 8j) a unit vector that has the opposite direction of the vector a is: a '= (1/17) * (15i - 8j)
