An impulse I is applied at the end of a uniform rod if mass m. then :
KE of translation of the rod isl22m
KE of rotation of the rod is 3l22m
KE of the rod is 2l2m
all of these
from conxervation of linear momentum the rod also has the same linear momentum I and kinetic of transtion is l22m from coservation of angular momentum L= Il=ml23ω ω=3Iml; rotational kinetic energy 12Lω= 12 I l3Iml=3I22m
