An astronaut practicing manoeuvring in space is startled to find she has drifted 65.67 m from her spaceship. Fortunately she knows that firing her thrusters’ pistol in the proper direction can get her safely back in no time. If she has a mass of 75.5 Kg and her thrusters pistol expels 35.3 g of hot gas at 555 m/s. How long will it take her to obtain back to the spaceship? Assuming she points it in the correct direction.
