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...
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?
Sorry I have no idea.
