Object of mass m is starting from the surface of spherical planet of mass m and radius r.
the object's distance from the center of the planet at time t is r(t)=k(t^p) (k and p are constants, t> 0)
(a) find acceleration, determine k and p.
(b) what happens to the velocity as t approaches infinity?
(c) determine escape velocity from earth's surface with previous results.
