A rain drop falling vertically under gravity gathers moisture from the atmosphere at a rate given by =kt*, where m is the instantaneous mass, t is time and k is a constant. The dt equation of motion of the rain drop is dvdm m+ mg If the drop starts falling at t =0, with zero initial velocity and initial mass mo (given: mo =2 gm, k = 12 gm/s' and g= 1000 cm/s*), the velocity (v) of the drop after one second is (A) 250 cm/s (B) 500 cm/s (C) 750 cm/s D) 1000 cm/s

    I won't say it's a hard, but a good question, cause it's application if one topic (mathematical physics ) into another(mechanics). clear the concepts, things will flow smooth.
