a lighter body and a heavier body have same momentum.which has greater kinetic energy?justify
Asked by nishmita bandekar | 17th Jan, 2011, 12:00: AM
KE = mv2/2 = p2/2m .. where p = mv is linear momentum.
Since for same momentum KE is inversely propotional to the mass, KE of lighter body is greater than that of heavier body.
