Earlier in the course we introduced the constant acceleration formulas (kinetic equations) vo,=at, x=xo +vot +1/2at2, ect, which are valid when the acceleration vector of mass m is constant.
For which of the following two situations is the acceleration vector constant so that these formulas are valid?
I.) A satellite of mass m in circular orbit of radius R around a planet of mass M.
II.) A mass m is released from rest at a point in space 32,000 km above the surface of the earth (32,000 is five times the radius of the Earth). It falls straight towards the center of the Earth and strikes the surface after falling for 2.7 hours.
The available answers are
A) both situations B) neither situation C) only situation I D) only situation II
