Raindrop – Variable Mass
Consider a raindrop falling through a cloud of tiny water droplets. Some of these tiny droplets get attached to this raindrop as it falls increasing its mass. Assume constant growth in the mass of the raindrop as a function of distance x of fall. Find out the acceleration of the raindrop assuming it to be constant.

Prove that, \[\scriptscriptstyle\left[ x \right] + \left[ {x + \frac{1}{n}} \right] + \left[ {x + \frac{2}{n}} \right] + ………….. + \left[ {x + \frac{{n – 1}}{n}} \right] = \left[ {nx} \right]\]
