Answer:
341.46miles
Explanation:
Find the diagram attachment.
To get the displacement D, we will use the cosine rule as shown;
D² = 200²+150²-2(160)(400)cos65°
D² = 40000+22500-128000cos65°
D² = 62500+54095.14
D² = 116595.14
D = √116595.14
D= 341.46 miles
Hence the plane final displacement is 341.46miles
1. 742.57m/s if it has a constant speed and 1485.15m/s if it's accelerating from 0m/s
2. 132m/s
