on Planet X, an object weights 18 N. On planet B where the magnitude of the free-fall acceleration is 1.87g (where g=9.8m/s^2 is the gravitational acceleration on Earth), the object weighs 36.9 N
The acceleration of gravity is 9.8m/s^2.
What is the mass of the object be on Earth?
Answer in units of kg.
