A body is dropped (initial velocity being 0) fromn a distance ro from the earth's center. Ignoring air resistance, the distance of this object from the earth's center r(t) satisfies the following equation K dt2 where K > 0 is a constant. Show that the body reaches the height r < ro at time (Vrro - + ro arccos. 2K Hint: this is a reducible 2nd-order ODE, see Sec. 1.6. You may want to use r = ro cos? 8 to evaluate f /r/(ro – r) dr.
