Kinetic energy K (Chapter 7) has dimensions kg · m2/s2. It can be written in terms of the momentum p (Chapter 9) and mass m as
K=p22mK=p^2/2m
(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?
