I know that the answer is a but what are the steps of solving it?? Q7. A plane leaves the airport and flies 68.0° east of north and travels 170 km. Then it changes direction of motion to fly 48.0° south of east, and travels 230 km. Finally, it makes an immediate emergency landing on the ground. When the airport sends out a rescue team, how far the team flies to go directly to this plane? A) 329 knm B)...
I know that the answer is a but what are the steps of solving it?? Q11 A fish swimming in a horizontal plane has an initial velocity v, (4.0 i+1.0 j) m/s at a point in the ocean.
