Question

Vector A is 3.00 units in length and points along the positive x-axis. Vector B is 4.00 units in length and points along the negative y-axis. Use graphical methods to find the magnitude and direction of the following vectors:

Answer 1

Answer:

The resultant vector has a magnitude of 5units in the positive x and negative y axis

Explanation:

from Pythagoras theorem

z² = x² + y²

z² = (3)² + (4)² = 25

z = 5units

direction = theta =

cos (theta) = 4/5

theta = arccos (0.8)

theta = 40.97°
