Question:

(a) Show that the kinetic energy K and the momentum magnitude p of a particle with mass m are related by K = p2/2m.
(b) A 0.040-kg cardinal (Richmondena cardinalis) and a 0.145-kg baseball have the same kinetic energy. Which has the greater magnitude of moment? What is the ratio of the cardinal's magnitude of momentum to the baseball's?
(c) A 700-N man and a 450-N woman have the same momentum. Who has the greater kinetic energy? What is the ratio of the man's kinetic energy to that of the woman?
