Answer 1

Step-by-step explanation:

9a) Velocity North

30 m/s * Sine(60) = 25.98076.. m/s

9b) Distance North

25.98076 m/s * (3 hour) but we need hours in seconds b/c that's our velocity units

25.98076 m/s * 10800 s = 280,592.23 m

9c) Velocity East

30 m/s * Cosine(60) = 15 m/s

9d) Distance East

15 m/s * (3 hours)

15 m/s * 10800 s = 162,000 m

9e) Total displacement ( total distance also known as magnitude)

Total Distance =
`\sqrt{(Distant North)^(2) + (Distant East)^(2) }`

TD =
`\sqrt{280592.23^(2) + 162000^(2) }`

TD = 323999.99 m

let's round it to 324,000 m

324 Km
