Question

numeric answers with units
in some problems, you will be required to enter the numerical value of your answer along with the corresponding units. you can enter only numeric values (including scientific notation), as opposed to full - calculations or algebraic expressions. the same grading, tolerance, and significant figure rules apply as before for numeric answers.
unless the instructions explicitly ask you to use a specific unit in your answer, you are free to enter any equivalent unit within the same unit system given in the problem (e.g., if the answer is 1 m, you may also enter 100 cm since those quantities are equivalent). in general, just be sure to use the appropriate abbreviations and prefixes for units (for a list of recognized units in mastering, feel free to reference acceptable units).
note that for compound units, you must use explicit multiplication between the units. for instance, newton - meter can be entered as n·m or n - m, but not nm.

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 kg to g

$7.2\times10^{-3}\ \text{kg} = 7.2\times10^{-3}\times1000\ \text{g} = 7.2\ \text{g}$

Step2: Determine equivalent momentum

$7.2\times10^{-3}\ \text{kg·m/s} = 7.2\ \text{g·m/s}$

Answer:

7.2 g·m/s
