b. Let East be defined as the positive direction for velocity.
A motorbike is travelling to the east at 50 ms
Calculate the velocity of the motorbike relative to the car. (2 marks)
--- 4 WORK AREA LINES (style=blank) ---
Let east be the positive direction and west be the negative direction.
Therefore, the velocity of the motorbike relative to the car is 110 ms
Plane A is flying due north at 300 kmh
Calculate the velocity of plane B as measured by the pilots on plane B? (3 marks)
