An object with a mass of 6 kg is thrown straight upward on Earth at a speed of 46.46 m/s. Due to air resistance, i.e., non-conservative work, it only reaches a maximum displacement of 45 meters. If the object were thrown at the same speed straight upwards on another planet where the mass of the planet was a factor of 3.4 larger than that of earth and its radius was a factor of 2.5 smaller than earth, what would its maximum vertical displacement be, in meters, on this new planet if the amount of energy lost to non-conservative forces was a factor of 2 smaller than that of earth?
