Chapter 11.2, Problem 34E

VelocityThe speed of an airplane is 300 mi/h relative to the air. The wind is blowing due north with a speed of 30 mi/h. In what direction should the airplane head in order to arrive at a point due west of its location?

A nuclear submarine approaches the surface of the ocean at 22.2 km/h and at an angle of 16.7° with the surface. What are the components of its velocity? See the figure to the right. First, setup a vector to represent the situation with the angle in standard position. The magnitude is km/hr and the angle is 0- (Do not include the degree symbol in your answer.) GELL CU 22.2 km 16.7

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] B A
