Planet X

  1. Nov 7, 2009 #1
    On planet X, an object weights 18.6N.
    Planet B, the magnitude of the free-fall acceleration is 1.42g (g=9.8m/s2) is the gravitational acceleration on earth)
    the object weights 29.8N
    acceleration of gravity is 9.8 m/s2.

    a) what is the mass (kg) of the object on planet X?

    b) what is the freefall acceleration on planet X? (m/s2)

    If I understand your question correct, you are asking:
    If an object weight 18.6N on X and 29.8N on B, and acceleration on B is 1.42g, find (a) and (b)

    You might want to try doing the problem yourself using the simple equation F=ma, or Force (newtons) = Mass (kg) * Acceleration (m/s^2), remembering that mass is constant on any planet but weight is not.
