A woman walks 4 km towards the east and then walks 8 km towards the north. Apply the tail to tip method to find the net displacement. Check your result with the parallelogram method. On Mars’ surface, a vehicle travels at a distance of 38 m at an angle of 180°. Then, it turns and travels 66 m of distance at an angle of 210°. What was its displacement from the origin point? Apply the tail to tip method to...
