Congratulations! You're the first person to step foot on a new planet. Standing on the planet's surface, you step on a scale and measure your weight to be 500 N. If you know that your mass is 50 kg, and the radius of the planet is 4,500 km, what is the mass of the planet (in Earth Masses where 1 Earth Mass = 5.97E24 kg)? Provide your answer as a positive number with 1 decimal place (e.g. 1.2). Do not write the units (e.g. s or m or m/s etc.) in the answer box.
