v = speed
v (or v )= velocity
A bird flies 100 m due east, then 200 m 45o north of west. Draw and measure the net displacement.
Determine the net displacement
A car travels 500 km at an angle 30o north of east. Calculate its x and y displacement.
sin q = opposite = o
cos q = adjacent = a
tan q = opposite = o
(Ans: 30.0 km, -38.5o)
(Ans: 960 km, -51o)
