After completing a turn, a cyclist is travelling west at 30 km/h. If his change in velocity was 10km/h [S], what is his initial velocity? Include a diagram.

A plane is flying to a city 716 km directly north of its initial location. Therefore the only component of the planes velocity relative to the earth most always be north The plane maintains a speed of 203 km/h relative to the air during its flight. The air is not standing still but has speed of 51.5 km/h relative to the earth. .(Let trhe +x-axis point East and the and the +y-axis point North) Let p=Plane, a =Air. e=Earth Using double subscript notation and write the vector components for the velocity of the Plane relative to the Earth
