Solution

Q1.

A is 15 degrees east of north

A is 75 degrees north of east

B is 24 degrees south of east.

B is 66 degrees east of south.

C is 25 degree south of west.

C is 65 degree west of south.

D is 30 degree west of north

D is 60 degree north of west.

Q2. vector given is 8.2 m/s at 55 degree north of east

then angle made by this vector with north=90-55=35 degrees

then north component=8.2*cos(35)=6.717 m/s

Q3. angle made with east=55 degrees

then east component=8.2*cos(55)=4.7033 m/s
