A velocity of magnitude 40m/s is directed at an angle of 40° east of north and draw a vector to present velocity
To draw a vector to represent the velocity, you will need to use a scale and a protractor.
First, mark a point on a piece of paper to serve as the starting point (origin) of your vector. This can be any convenient location.
Using a ruler and the chosen scale, measure a distance of 40 units (for example, 1 cm represents 10 m) in the north direction from the starting point and make a mark. This represents the magnitude of the velocity.
Next, using a protractor, align its base with the north direction (straight up on the paper) and rotate it clockwise by 40 degrees (east of north). This will be the direction of the velocity.
From the mark you made representing the magnitude, draw a straight line in the direction indicated by the protractor. The line should be long enough to represent the chosen scale for the magnitude.
Finally, label the arrowhead of the line with a "v" to indicate the vector represents velocity.
Now, you have drawn a vector to represent a velocity of magnitude 40 m/s at an angle of 40° east of north.
