1. The surface area of a raindrop increases as it falls. Therefore, the air resistance to its falling increases as it falls until it reaches terminal velocity where the velocity becomes a constant. Assume that a raindrop has an initial velocity of -10 m/s and its acceleration isa(t) = 0.9t - 9 0 ≤ t ≤ 10 0 t > 10Define a piece-wise function that represents the velocity, in m/sec, of the raindrop at time t seconds.

The velocity v(t) of a falling raindrop at time t is modeled by the equationv(t)=v^*(1-e^-g t / v^*) where g is the acceleration due to gravity and v * is theterminal velocity of the raindrop. (a) Find limt →∞ v(t) . (b) For a large raindrop in moderate rainfall, a typical terminal velocity is 7.5 m / s . How long does it take for the velocity of such a raindrop to reach 99% of its terminal velocity? (Take g=9.8 m / s^2 . ) | Numerade

A raindrop of initial mass M0 starts falling from rest under the influence of gravity. Assume that the drop gains mass from the cloud at a rate proportional to the product of its instantaneous mass and its instantaneous velocity: (d M)/(d t)=k M V where k is a constant. Show that the speed of the drop eventually becomes effectively constant, and give an expression for the terminal speed. Neglect air resistance. | Numerade
