Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2.

Two objects that only have the force of gravity acting on them, will fall with the same acceleration g=9.8ms2; g=32.2fts2 and will therefore hit the ground at the same time.

When you drop a feather, air resistance acts on all the surfaces of the feather. This causes the feather to slow down.

Air resistance depends on two factors: the speed of the object (increased for example by throwing it), and its surface area.

hope this can give u a little bet more to know about how to get ur answer :P 

have a gud day and gud luck!

answer; i believe that the correct answer is (d) a very small amount of mass

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
