Homework Statement A 92 kg man weighs 189 Newtons on the surface of an unknown planet. What ist he acceleration of gravity on this planet? Basically, I thought the formula to finding the gravitational force was G(gm)/r^2, but I'm missing the distance that the man from the planets center...

Oh ok thanks! I forgot about centripetal force, I figured it out.Sorry I'm new to these forums, so it's all about attempting before asking.

Homework Statement A 3.0 kg object rotates on a circular platform 1.5 m from the center. The tangential velocity of the object is 10.0 m/s. If the mass is attached to a spring scale, what force will the scale read? Homework Equations Sorry I have no idea. The Attempt at a Solution...
