A cylindrically shaped rocket of radius 1.25 m travels horizontally through the earth's atmosphere. The rocket's drag coefficient, determined experimentally in a wind tunnel, is 0.28. Calculate the thrust produced by the rocket engine in order to travel at a constant speed of 175 m/s in a region of the atmosphere where the air density is 0.825 kg/m3.
