A man walks the distance of 8km in a direction of 20degrees east the walks another 6km in a direction 50degrees south east. Using vector diagrams find the magnitude and direction of the final displacement relative to the starting point.
What grade is this?posted by Mina
we can't do a vector diagram here.
draw an arrow E, of length to represent 8 units. Then from the tip of the arrow, draw a vector 50 deg south of East of length 6. Now, measure the length from the original origin to the final tip. Convert that length to km.posted by bobpursley
