A ball of mass 2 kg and another of mass 4 kg are dropped together from a...
This problem is a clear mix of motion under gravity i.e kinematics
and WPE. First we need to apply formula of velocity after falling through
height h then we can find ratio of K.E. Since formula of velocity is
independent of mass and both are falling
through same height so ratio of kinetic energy will only be the ratio of their
masses only
