I know the 90* and 270* have a 4N resultant, but my scale drawing is left with a quadrilateral and I'm a little stuck there, any help would be appreciated.

Calculate the force needed to bring a 1070–kg car to rest from a speed of 89.0 km/h in a distance of 110 m (a fairly typical distance for a non-panic stop). Suppose instead the car...
