Question

1. A drone is launched with a velocity of 22m/s, 254. Three minutes after the drone is launched it suddenly changed its course to 22m/s, 89 to avoid high trees on its way. Then, it finally goes back at a rate of 15m/s, 320. Calculate for the total resultant vector of the drone.
2. Pan am Flight 7 was one of the famous planes to disappear into the Bermuda Triangle, which is en route from San Francisco to Hawaii . The first route is due west for 998km; then it took a detour southeast for 722km; and the its final route is at 53° north of west, the crash site in the Pacific ocean, for 842 What is the plane’s total displacement?
3. CIA and NSA launched a hiring program to new agents: to crack the safehouse of the nuclear launch codes. They were given hacking tools and random displacement as a starting point. Agent 1 is directed to 70m, 254; Agent 2 is directed to 93m, 130 and Agent 3 to 63m due south. The three displacements lead to the point in the field where the key to the nuclear launch codes of the United States is kept. Two agents did not use their noggin’ and started measuring immediately, but the winner of the code first calculated where to go. What was the calculated resultant of the winner?
   

1. 244 degrees, 89 degrees, 320 degrees

2. 842 degrees

3. 254 degrees, 130 degrees
