Two objects (16 kg and 2 kg ) are released simultaneously on a 6 meter long frictionless inclined plane that makes an angle of 30 degrees with the horizontal which one reaches the bottom of the hill at a greater speed

Didn't Galileo do this experiment? Maybe the most famous scientific experiment is Galileo Galilei's dropping objects from the leaning tower of Pisa in order to prove that all objects fall at the same rate, whatever their mass. ... Galileo used inclined planes for his experiment to slow the acceleration enough so that the elapsed time could be measured.
