Q. A body of mass 1 kg is thrown upwards with a velocity 20 m/s. It momentarily comes to rest after attaining a height of 18 m. How much energy is lost due to air friction? (g = 10 m/s2

AIPMT/NEET 2009 | W.P.E Q 2 | We can apply work energy theorem in this case as info about initial and final velocity is given . Change in an object’s kinetic energy is equal to the net work done on the object. Conservative and non-conservative , both type of forces are present . height is given so we can easily calculate work done by gravity although it will be negative .
