    2. Sebuah mobil bermassa 700 kg bergerak dengan kecepatan 72 km/jam bergerak dengan kecepatan 72 km/jam. Momentum mobil tersebut adalah .............. 

    • 10000 kg m / s

    • 11000 kg m/s

    • 12000 kg m/s

    • 13000 kg m/s

    • 14000 kg m/s

    Correct Answer
    A. 14000 kg m/s
    Explanation
    The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the mass of the car is given as 700 kg and the velocity is given as 72 km/h. To convert the velocity to m/s, we divide it by 3.6 (1 km/h = 0.2778 m/s). So, the velocity becomes 20 m/s. Multiplying the mass and velocity, we get 700 kg * 20 m/s = 14000 kg m/s. Therefore, the correct answer is 14000 kg m/s.

  • 4. 

    Sebuah mobil yang berlari cepat mempunyai momentum yang ...................  dibandingkan dengan mobil yang lambat dengan massa yang sama

    • Beraturan

    • Tidak beraturan

    • Lebih besar

    • Lebih kecil

    • Kekal

    Correct Answer
    A. Lebih besar
    Explanation
    A fast-moving car has a greater momentum compared to a slow-moving car with the same mass. Momentum is directly proportional to the velocity of an object. Since the fast car is moving at a higher velocity, its momentum will be greater than the slow car. Therefore, the correct answer is "lebih besar" which means "greater" in English.

    Rate this question:

  • 5. 

    1.Dari pernyataan berikut yang merupakan pengertian momentum yang benar adalah .............

    • Hasil perkalian massa dan percepatan suatu benda

    • Hasil perkalian antara gaya dan interval waktu selama gaya bekerja pada benda

    • Energi yang dimiliki oleh benda yang bergerak

    • Hasil perkalian kecepatan dan gaya yang bekerja pada suatu benda

    • Hasil perkalian massa dan kecepatan suatu benda

    Correct Answer
    A. Hasil perkalian massa dan kecepatan suatu benda
    Explanation
    The correct answer is "hasil perkalian massa dan kecepatan suatu benda" because momentum is defined as the product of an object's mass and velocity.

    Rate this question:

  • 6. 

    Sebuah benda bermassa 500 gr bergerak dengan kelajuan 6 m/s, besar momentum benda tersebut adalah ...............

    • 0,5 kg m/s

    • 1 kg m/s

    • 1,4 kg m.s

    • 2,5 kg m/s

    • 3 kg m/s

    Correct Answer
    A. 3 kg m/s
    Explanation
    The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the mass of the object is given as 500 grams, which is equal to 0.5 kilograms. The velocity of the object is given as 6 m/s. Therefore, the momentum of the object can be calculated as 0.5 kg * 6 m/s = 3 kg m/s.

    Rate this question:

  • 7. 

    Salah satu cara untuk merubah momentum benda adalah, kecuali ............

    • Dibutuhkan sebuah gaya untuk menaikkan momentum

    • Dibutuhkan sebuah gaya untuk menurunkan momentum

    • Merubah arahnya

    • Mengubah gaya yang bekerja padanya

    • Membutuhkan gaya

    Correct Answer
    A. Merubah arahnya
    Explanation
    One way to change the momentum of an object is by changing its direction. When the direction of an object changes, its momentum also changes. This can be achieved by applying a force in a different direction, causing the object to change its path and thus altering its momentum.

    Rate this question:

  • 8. 

    Dimensi momentum atau impuls adalah ...................

    • M L T^-1

    • M L T^-2

    • M L^-1 T^-1

    • M L^-2 T

    • M L^2T^2

    Correct Answer
    A. M L T^-1
    Explanation
    The correct answer is M L T^-1. This is because momentum or impulse is defined as the product of an object's mass and its velocity. The units for mass are M, and the units for velocity are L T^-1. Therefore, the units for momentum or impulse are M L T^-1.

    Makin kecil momentum suatu benda makin ...............

    • Sulit untuk menghentikannya

    • Mudah untuk menghentikannya

    • Cepat pergerakannya

    • Lambat Pergerakannya

    • Besar impulsnya

    Correct Answer
    A. Mudah untuk menghentikannya
    Explanation
    The correct answer is "Mudah untuk menghentikannya" (Easy to stop it). This is because momentum is directly proportional to the mass and velocity of an object. When the momentum of an object is small, it means that either the mass or the velocity (or both) of the object is small. Therefore, it would be easier to stop the object as it would have less inertia and less resistance to changes in its motion.

  • 10. 

    Dalam waktu 0,01 sekon sebuah benda mengalami perubahan momentum sebesar 4 kg m/s. Besar gaya yang mengakibatkan perubahan tersebut adalah ...........

    • 0,04 N

    • 0,4 N

    • 4 N

    • 40 N

    • 400 N

    Correct Answer
    A. 400 N
    Explanation
    The correct answer is 400 N. This is because the formula to calculate force is force = change in momentum / time. Given that the change in momentum is 4 kg m/s and the time is 0.01 seconds, we can calculate the force as 4 kg m/s / 0.01 s = 400 N.
