N. The figure below shows a trajectory of a satellite that is launched from point A using a rocket, to point
C in space, this movement AC took a certain time. Then it moved towards point B [angle ACB is 90
degrees] in 1.4 hours. At this moment of time, the distance between the launching point and the satellite
measured in travelling hours, AB = 1.9 hours. The angle CAB = 50.0°. Write down the vectors CB
and AB in terms of i and j components [Cartesian format]. Write down an equation relating AC, AB
and CB as vectors, then find the vertical travelling duration points A and C, or the vector AC? [Hint:
you can simplify the problem by rotating the triangle such that AC coincides with the y-axis]
