2- A test projectile is fired horizontally into a viscous liquid with a velocity 100 m/s. The retarding force is proportional to the square of the velocity, so that the acceleration becomes a =-0.8v². Derive expressions for the distance D traveled in the liquid and the corresponding time t required to reduce the velocity to 50 m/s. Neglect any vertical motion. {0.66 m, 0.0125s}
