A ball of mass 2kg and another of mass 4kg are dropped together from a 60feet tall building. After a fall of 30 feet each towards earth, their respective kinetic energies will be in the ration of ___________ Correct Answer 1:2

Both balls attain same velocity v after falling through 30 feet height. E1/E2 = (1/2 m1 (v1)2)/(1/2 m2 (v2)2) = (2v2)/(4v2)=1/2=1:2.
