Kinetic energy K (Chapter 7) has dimensions kg • m2/s2. It can be written in terms of the momentum p (Chapter 9) and mass in as
K=p2/2m
(a) Determine the proper units for momentum using dimensional analysis.
b) The unit of force is the newton N, where 1 N =1 kg • m/s2. What are the units of momentum p in terms of a newton and another fundamental SI unit?
