Assume that a cloud consists of tiny water droplets suspended (uniformly distributed, and at rest) in air, and consider a raindrop falling through them. what is the acceleration of the raindrop? (assume that when the raindrop hits a water droplet, the droplet’s water gets added to the raindrop. also, assume that the raindrop is spherical at all times.)

Araindrop of mass m0, starting from rest, falls under the influence of gravity. assume that as the raindrop travels through the clouds, it gains mass at a rate proportional to the momentum of the raindrop, dmr = kmrvr, where mr is the in- dt stantaneous mass of the raindrop, vr is the instantaneous velocity of the raindrop, 5 and k is a constant with unit [m−1]. you may neglect air resistance. (a) derive a differential equation for the raindrop’s accelerations dvr in terms of dt k, g, dt and the raindrop’s instantaneous velocity vr . express your answer using some or all of the following variables: k,g for the gravitational acceleration and vr, the raindrop’s instantaneous velocity.

In a rocket-propulsion problem the mass is variable. another such problem is a raindrop falling through a cloud of small water droplets. some of these small droplets adhere to the raindrop, thereby increasing its mass as it falls. the force on the raindrop is fext=dpdt=mdvdt+vdmdt suppose the mass of the raindrop depends on the distance x that it has fallen. then m=kx, wherek is a constant, and dm/dt=kv. this gives, since fext=mg, mg=mdvdt+v(kv) or, dividing by k, xg=xdvdt+v2 this is a differential equation that has a solution of the form v=at, where a is the acceleration and is constant. take the initial velocity of the raindrop to be zero. a) using the proposed solution for v, find the acceleration a. b) find the distance the raindrop has fallen in t = 2.00s . c) given that k = 2.00g/m , find the mass of the raindrop at t = 2.00s
