Questions: The momentum of an object is determined to be 7.2 x 10^-3 kg · m / s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g).

Transcript text: The momentum of an object is determined to be $7.2 \times 10^{-3} \mathrm{~kg} \cdot \mathrm{~m} / \mathrm{n}$. Express this quantity as provided or use any equivalent unit. (Note: $1 \mathrm{~kg}=1000 \mathrm{~g}$ ).

Solution

Solution Steps

Step 1: Identify the Given Quantity

The momentum of the object is given as $7.2 \times 10^{-3} \, \mathrm{kg} \cdot \mathrm{m} / \mathrm{s}$.

Step 2: Convert Kilograms to Grams

Since $1 \, \mathrm{kg} = 1000 \, \mathrm{g}$, convert the mass unit from kilograms to grams: \[ 7.2 \times 10^{-3} \, \mathrm{kg} = 7.2 \times 10^{-3} \times 1000 \, \mathrm{g} = 7.2 \, \mathrm{g} \]

Step 3: Express Momentum in Equivalent Units

Express the momentum using grams: \[ 7.2 \, \mathrm{g} \cdot \mathrm{m} / \mathrm{s} \]
