Question

The momentum of an object is determined to be 7.2 ×× 10-3 kg⋅m/skg⋅m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kgkg = 1000 gg).

Answer 1

The momentum of the object is 7.2 × 10^-3 kg·m/s, which is equivalent to 7.2 g·m/s when the mass is converted from kilograms to grams.

Step-by-step explanation:

The momentum of an object is defined as the product of its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction. The magnitude of the given object's momentum is 7.2 × 10-3 kg·m/s. To express this quantity in equivalent units, we can convert the mass from kilograms to grams by noting that 1 kg equals 1000 grams. Thus, the momentum in grams·m/s can be calculated as (7.2 × 10-3 kg) × (1000 g/kg) = 7.2 g·m/s.

Answer 2

Momentum, p = 720 g-cm/s

Step-by-step explanation:

The momentum of an object is determined to be,

`p=7.2* 10^(-3)\ kg-m/s`

We need to express this quantity in any equivalent units. We know that the conversions are as follows :

1 kg = 1000 g

and 1 m = 100 cm

`p=7.2* 10^(-3)\ kg-m/s=7.2* 10^(-3)* (1000\ g)* (100\ cm)/s`

p = 720 g-cm/s

So, the momentum of an object in any equivalent unit is 720 g-cm/s. Hence, this is the required solution.
