Answer:
The correct option is;
Magnitude of 8 and direction angle equal to 0°
Explanation:
The magnitude of a vector is given by the distance from the initial point of the vector, (which id the starting point) to the final point of the vector, which is the end point of the vector
From the graph, the starting point of the vector = (-2, 2·√2)
The end point of the vector from the graph = (6, 2·√2)
The magnitude of the vector = √(6 - (-2))² = 6 - (-2) = 6 + 2 = 8
The direction of the vector = arctan((The y-component of the vector)/(The y-component of the vector))
∴ The direction of the given horizontal vector = arctan(0/8) = arctan(0) = 0°
