Problem
A stone is dropped from a balcony and its motion is analysed by ignoring air resistance. Why is air resistance neglected in such classroom calculations?
(a) Because air resistance only affects horizontal motion and not vertical motion
(b) Because for a dense stone the effect of air resistance is small compared with its weight
(c) Because air exerts an upward force equal to the weight of the stone
(d) Because the equations of motion cannot be used when air resistance is present
