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

Answer 1

To express the momentum of an object with a mass of 7.2 × 10^-3 kg • m/s, we can use an equivalent unit by multiplying the mass by 1000 (1 kg = 1000 g).

7.2 × 10^-3 kg • m/s = 7.2 × 10^-3 kg * 1000 g/kg • m/s

= 7.2 × 10^-3 * 1000 g • m/s

= 7.2 g • m/s
