**1. The problem statement, all variables and given/known data**

Express the units of angular momentum (a) using only the fundamental units kilogram, meter, and second; (b) in a form involving newtons; (c) in a form involving joules.

**3. The attempt at a solution**

a) L = r x p = r x mv = Iω

This can be simplified to kgm^{2}/s

b) L = r x p = r x mv

I express r in meter m , m in kg and v in ms^{-1}

what I got was m^{2}kg/s

I have to convert it to n.m.s
