SI units are the universally accepted standard units to measure quantity.

There are 7 basic parameters with each having an SI unit of its own

Kilograms are one of these SI units. Kilograms are used to measure Mass.

All the other units used to measure mass are derived from this basic unit.

eg:1000 g is equivalent to 1 kg

therefore quantity used to measure in kg is Mass

2) Two students are running in a cross country race. One has a mass of 60 kg, while the other has a mass of 70 kg. If they are b
Iteru [2.4K]

Answer:

The second student with mass 70kg has more momentum

Explanation:

Using the formula:

p = m × v

Where;

p = momentum (kgm/s)

m = mass (kg)

v = velocity (m/s)

According to this question, two students are running in a cross country race.

Student 1 has the following; m = 60kg, v = 7m/s

Student 2 has the following; m = 70kg, v = 7m/s

Using p = mv

Student 1, p = 60 × 7 = 420 kgm/s

Student 2, p = 70 × 7 = 490 kgm/s

From the result of the above calculations, student 2 with mass 70kg has more momentum.
