Kinetic energy K has dimensions kg•m2/s2. It can be written in terms of the momentum p and mass m 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?
