Question

the units of momentum are: multiple choice n m/s n·m/s kg·m/s

Explanation:

Momentum (\(p\)) is defined as \(p = mv\), where \(m\) is mass (units: kg) and \(v\) is velocity (units: m/s). Multiplying these units: \(kg\times\frac{m}{s}=kg\cdot m/s\). \(N\) is force, \(m/s\) is velocity, and \(N\cdot m/s\) is not momentum’s unit.

Answer:

D. kg·m/s (assuming the last option is D; if options are labeled differently, adjust the label but keep the unit text)
