1. The velocity, v, of an object moving through a fluid can be modeled by the drag equation dv dt =-kv2 where k is a constant. An object moving through the water has an initial velocity, vo, in the interval of 16 m/sec S vo $ 20 m/sec. After 2.0 seconds, the velocity has decreased to v, in the interval of 8 m/sec S v, $ 12 m/sec. a. Find the equation that models the velocity of the object, v at any time, t (choose a value of vo and v, from the given intervals). By using an appropriate analytical method, solve the derived model, explain the reason for the selection of the method and discuss the behavior of the velocity, v(t) for interval of 0
