A projectile is ejected into an experimental fluid at time t = 0. The initial speed is v₀ and the angle to the horizontal is θ. The drag on the projectile results in an acceleration term a_D = -kv, where k is a constant and v is the velocity of the projectile. Determine the x- and y-components of both the velocity and displacement as functions of time. What is the terminal velocity? Include the effects of gravitational acceleration.
