Q. It is well known that a raindrop or a small pebble falls under the influence of the downward gravitational force and the opposing resistive force. The resistive force is known to be proportional to the speed of the drop. Consider a drop or small pebble of 1 g falling (from rest) from a diff of height 1.00 km. It hits the ground with a speed of 50.0 m

s^{- 1}

. What is the work done by the unknown resistive force?
