1.	A body P of mass ‘m’ is moving with a velocity ’v’. Another body Q of mass m/2 is moving with a velocity’2v’. Which of the body is likely to have more kinetic energy? Support your answer by proper calculations.
Answer» y p.K.E=1/2mv^2For body QK.E=1/2×m/2×(2V)^2 =m/4×4v^2 =mv^2so for body Q K.E is double than P.
