(a) Two springs have force constants \( \mathrm{K}_{1} \) and \( \mathrm{K}_{2}\left(\mathrm{~K}_{1}\mathrm{K}_{2}\right) \). On which spring is more work done when they are stretched by the same force ?
\( \mathrm{P} \)
(b) Two masses one \( \mathrm{n} \) times the other have equal K.E. How do their momenta compare ?
