quantities (jelaskan satuan dan dimensi dari):
a. specific mass (massa jenis)b. velocity (kecepatan)
c. potential energy (energi potensial)
2. [score10] A vernier caliper has a result of measurement as
shown in picture. How do we report this result?(sebuah jangka sorong mendapatkan hasil
pengukuran seperti gambar. Berapakah hasil pengukuran tersebut?)
3. [score15] Period to make a vibration is arranged by equationk
mT
2
. IfTis time (second) and
m is mass (kg), kis a constant. What is the dimension ofk? (Perioda suatu
getaran di susun dengan persamaank
mT
2.Apakah dimensi dari k?)
4. [score20] Three force vectors with 6N, 4N and 2N are shown in picture.
Find the components of each vector and what is the resultant of the vector?
(Tiga vector gaya dengan 6N, 4N dan 2N seperti gambar. Tentukan
komponen tiap vector dan berapa resultan vector tersebut?)
5. [score15] A car is moving in the circular street as
shown in picture. The diameter is 400 meter and it moves for 80 second
following half of circle. What are its average velocity and average speed?(Mobil bergerak pada jalan melingkar seperti gambar. Diameter jalan
melingkar 400 m dan mobil bergerak selama 80 detik mengikuti
lingkaran. Berapakah kecepatan rata-rata dan kelajuan rata-ratanya?)
6. [score15] A car moves from P to Q with 20 m/s. A bus moves from Q to P with 30 m/s. After 80
second, they meet in somewhere between P and Q. What is the distance of PQ? (Mobil bergerak
dari P ke Q dengan 20 m/s. Bis bergerak dari Q ke P dengan 30 m/s. setelah 80 detik mobil dan
bis saling bertemu diantara P dan Q. Berapakah jarak P-Q?)
7. [score15] Someone is riding his bike with velocity of 5 m/s. He adds his velocity until 35 m/s
for 6 second. Make calculation of his acceleration and his distance! (seseorang bersepedadengan kecepatan 5 m/s. dia menambah kecepatannya hingga 35 m/s selama 6 detik. Hitung
percepatan dan kecepatan sepeda itu!)
8. [score15] A train will be arrived in a station. It comes with velocity of 60 m/s and then reducing
until 15 m/s. If it is happened for 15 second, what is its acceleration and its distance? (Kereta
sedang menuju stasiun. Kereta mula-mula berkecepatan 60 m/s kemudian berkurang hingga 15
m/s selama 15 detik. Berapakah pecepatan kereta dan jarak yang ditempuhnya?)
