If a cyclist in the Tour de France traveled southwest a distance of 12,250 meters in one hour, what would the velocity of the cyclist be?
1. If a cyclist in the Tour de France traveled southwest a distance of 12,250 meters in one hour, what would the velocity of the cyclist be?
Jawaban:
Kita tahu bahwa kecepatan diartikan sebagai laju jarak yang ditempuh per satuan waktu, jarak / waktu, serta memiliki kecepatan dan arah. Di sini, kita diberi tahu bahwa dalam waktu satu jam, pengendara sepeda menempuh jarak 12.250 meter. Jadi, kami tahu bahwa:
t = 1 jam
d = 12.250 m
Kita juga tahu bahwa ada 60 detik dalam satu menit dan 60 menit dalam satu jam, dan kita mungkin menginginkan kecepatan dalam satuan meter per detik, m / s. Jadi, mari gunakan persamaan yang relevan dan masukkan angka dan konversi unit kita:
v = d / t
= 12.250 m * 1 jam * 1 menit
1 jam 60 menit 60 detik
= 3.403 m / s barat daya
Jika Anda perlu melaporkan arah dalam satuan derajat atau radian, buat timur 0 ° atau 0 radian, dan putar 45 ° atau π / 4 radian 5 kali berlawanan arah jarum jam untuk mendapatkan 225 ° atau 5π / 4 radian.
2. A planet has a mass of 7 times of the earth's mass and its radius is 3 Times of the radius of the earth's if the acceleration of gravity of the earth's surface is g; the acceleration of gravity of the planet is
diket: Mx = 7 Mb
Rx = 3 Rb
gb = g
ditanya: gx ...?
jawab: gx
gx/gb = Mx . Rb²/Mb . Rx²
gx/g = 7 Mb . Rb²/Mb . (3 Rb)²
gx/g = 7 Mb . Rb²/Mb . 9 Rb²
gx = 7/9 g

8. A cyclist and bike have a total mass of 100 kg and a speed of 15 m/s. Calculate the kinetic energy.
mass total of cyclist and the bike = m = 100 kg
velocity = V = 15 m/s
kinetic energy = Ek = ..... ?
[tex]ek = \frac{1}{2} \times m\times {v}^{2} [/tex]
[tex]ek = \frac{1}{2} \times 100 \times {15}^{2} = 50 \times 225[/tex]
Ek=11250Joule
Jawaban:
Ek = 1/2 m. v^2
Penjelasan:
Ek = 1/2 . m . v^2
Ek = 1/2 . 100 . 15 . 15
Ek = 50 . 225
Ek = 11250 Joule

9. A loaded lift has a total mass of 1.5 t. Determine the force in the cables when: (a) The acceleration of 2.7 m/s² is upwards. (b) The acceleration of 1.7 m/s2 is downwards.
Jawaban:
(a) The acceleration of 2.7 m/s2 is upwards
10. what force is needed to give a mass of 20kg an acceleration of 5.0 m/s
Jawaban:
100 N
Penjelasan:
Rumusnya a=f/m
Caranya substitusi dulu hal yang diketahui yaitu massa dan akselerasi
5=f/20
langsung kali silang saja
F=20 X 5
=100 N
Hopefully can help you
Thank you
11. gerak spesifik permainan rounds
Jawaban:
Dalam permainan rounders Terdapat beberapa gerakan, di antaranya melempar, menangkap, memukul, dan lari. Rounders adalah permainan bola kecil dengan teknik dasar yang hampir sama dengan permainan kasti yaitu melempar, menangkap, dan memukul ditambah dengan ketrampilan mengetik dan menghindari sentuhan bola.

13. A cyclist completed 45% of his journey after cycling 18 km.11. What was the length of the whole journey?
[tex] \frac{45}{100} \: = \: \frac{18}{x} [/tex]
[tex]x \: = \: 18 \: \times \: \frac{100}{45} [/tex]
[tex]x \: = \: 2 \: \times \: 20[/tex]
[tex]x \: = \: 40 \: km[/tex]
Penjelasan dengan langkah-langkah:
[tex]45\% = 18km \\ 100\% = ....[/tex]
whole journey
[tex] = \frac{100\%}{45\%} \times 18 \\ = \frac{20}{9} \times 18 \\ = 40km[/tex]

18. father bought a new car . its wheel has 0.7m of radius. if the wheel rounds 1200x, find the distance of the car (in km)
Answer:
5,280 m
Explanation with steps:
wheel radius (r) = 0.7 m
number of wheel rounds = 1,200
wheel diameter
= 2 x r
= 2 x 0.7 m
= 1.4 m
wheel circumference
= π x diameter
= (22/7) x 1.4 m
= 4.4 m
so the distance traveled by the car is
= circumference x number of wheel rounds
= 4.4 m x 1,200
= 5,280 m
19. A car starts from rest and rolls down a hill with constant acceleration. It travels a distance of 500 m in 20 sec. Calculate its acceleration.
A car starts from rest and rolls down a hill with a constant acceleration. It covers a distance of 500 m in 20 seconds. So the acceleration is 1,25 m/s²
Discussion
Is known :
distance (s) = 500 m
time (t) = 20 second
Asked :
acceleration (a)?
Answered :
Find the speed first
v = s/t
v = 500/20
v = 25 m/s
Find acceleration
a = v/t
a = 25/20
a = 1,25 m/s²
Conclusion
So, the acceleration is 1,25 m/s²
