Aprojectile 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 ad = −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.
