Question

part c
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).

Explanation:

Step1: Convert kilograms to grams

We know that $1\ kg = 1000\ g$. So, $7.2\times10^{-3}\ kg\cdot m/s=(7.2\times10^{-3}\times1000)\ g\cdot m/s$.

Step2: Calculate the value

$7.2\times10^{-3}\times1000 = 7.2\times10^{-3 + 3}=7.2\ g\cdot m/s$.

Answer:

Value: $7.2$
Units: $g\cdot m/s$
