An airplane travels 200 miles due west, and then 150 miles 608 north of west. determine the resultant displacement.
1. An airplane travels 200 miles due west, and then 150 miles 608 north of west. determine the resultant displacement.
Consider X-axis as West - East.
Consider Y-axis as North - South.
The plane starts from O (0, 0).
First it goes 200 miles due West to A (- 200, 0).
Then it goes to B, say (p, q).
So, AB is 150 miles 60° North of West.
So, p - (- 200) = - 150 * cos 60°
Or, (p + 200) = - 150 * 1 / 2 = - 75
Or, p = (- 200 - 75)
Or, p = - 275
And, q - 0 = - 150 * sin 60°
Or, q = - 150 * (√3) / 2 = - 75√3
Or, q = - 75√3
Thus, final location of the aircraft = B (- 275, - 75√3).
Therefore, magnitude of resultant displacement = |√[{(- 275)^2} + {(- 75√3)^2}]| miles = √(75625 + 16875) miles = √92500 miles ≈ 304.138 miles.
And, direction of resultant displacement = arc tan {(- 75√3) / (- 275)} = arc tan {(3√3) / 11} = 25.284° North of West.
i copied this answer from a forum in quora, dont get me wrong. but the end results varies

4. 1. A car has mass 800 kg moves with initial velocity 36km/hours. How long car moves if after travels long 150.0 m, it’s velocity becomes 72 km/hours ?.
males ah pen pulang gk usah sekolah
Vo = 36 km/h >> 10m/sVt = 72 km/h >> 20m/s
s 150m
(I) a = ...?
(II) t = ...?
(I)
Vt² = Vo² + 2as
(20)² = (10)² + 2a . (150)
400 = 100 + 300a
300a = 300
a = 1 m/s²
(II)
Vt = Vo + at
20 = 10 + (1) .t
t = 20 - 10 = 10s
5. 1. in one hour,a car travelling at 70 miles per hour will go a shorter distance than a car travelling at 70 kilometres per hour (jawab betul atau salah)2. 45 miles: km3. 208 km: miles
false/salah. semoga bermanfaat1. True
3. 208 km = 208 × 1.000.000 = 208.000.000 miles
6. A car travels a distance of 540 km in 6 hours. what speed did it travel
Jawaban:
90 km/hour
Penjelasan dengan langkah-langkah:
540 km ÷6 hour= 90 km/hour
7. 3. A car is travelling at a speed shown in the speedometer below. Which of the following statements is true? a) The car travels 65 km in 1 hour.b) The car travels 35 km in 1/2 hour. c) The car travels 30 km in 1/2 hour. d) The car travels 75 km in 1 hour. Repost soal ini dan mohon jawabin ya jika nada jawabin dengan penjelasan saya akan bikin jawaban nya sebagai brain list.
Penjelasan dengan langkah-langkah:
di gambar soal menunjukkan
angka 70 km/jam =
35km/½jam.
opsiB
Jawaban:
B
Penjelasan dengan langkah-langkah:
70km/ 1 hour ÷ 2
=70km/60 minutes ÷ 2
=35/30minutes
Maaf kalo gk ngerti

13. The distance of City A and B is 600 km. Eren travels from City A to City B by car at 07.05 AM with speed 70 km/h. At the same time, Mikasa travels from City B to City A by car with speed 80 km/h. If the travels runs well, what time they will pass each other?
Jawaban:
they will pass each other at 11.05 AM
Penjelasan dengan langkah-langkah:
time pass they meet each other = 600 / 70+80
= 600 / 150= 4 hours
travels from 07.05Am + 4 hours = 11.05 Am

16. A bird leaves its nest and travels 18 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after x hours. a. What is the distance of the entire trip? ____miles b. How long does the entire trip take? ____ hours ____ minutes and ____ seconds
Jawaban:
a. 30 miles
b. 1 hour 40 minutes
Penjelasan dengan langkah-langkah:
dari soal diatas, satu satunya yang sama afalh total jarak tempuhnya. dari kejadian awal
s = v x t
s = 18X
dari kejadian kedua
s = 15X + 5
substitusi nilai s
15X + 5 = 18X
3X = 5
X = 1 hour 40 minutes
s = 30 miles
