5) A raindrop having no initial mass and zero velocity falls through a stationary cloud. It accumulates mass at a constant rate k. It is subject to air resistance having magnitude cv, where v is the speed of the raindrop and c is a constant. Find an expression for the velocity and position of the raindrop at time t.

A raindrop of mass 4.0 mg and radius 2.0 mm has acquired an electric charge of 15x10^-15 C. The raindrop is located at the bottom of a cloud that is 500 m above the surface of the earth where the electric potential is -10^9 V with respect to the ground. What is the ratio of the electric potential energy of the raindrop compared to the gravitational potential energy? ANS: -7.7x10^-4 I just don't know how to solve the problem.

Consider a spherical bacterium, with radius 1.7 μm , falling in water at 20° C. Find the terminal speed of the spherical bacterium in meters per second, ignoring the buoyant force on the bacterium and assuming Stokes' law for the viscous force. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be 1.3 × 103 kg/m3. The viscosity of water at 20 °C is...
