A rock is released from rest at a distance D = 3.5 X It)? rn above the ED113195 of the Earth as shown in the gure Useful constants for this problem are the universal gravitational constant G = 6.67 x 10'\" lefkgz, the mass ofthe Earth Me a 5.97 x [03\" kg, and the radius ofthe Earth Re : 6.33 r to\" m. 20) What is the speed of the rock. 1; 1' when it has fallen to a distance Df'4 above the surface of the Bath? a. at, = 5778 mt's b. u; = 8262 mfs c. v; = 4086 rat's d. v, = 22694 [W's e. v; = 11173 mfs 2 I) Planet llondo has the. same radius as the. earth but has a smaller mass- Suppose the some rock were released from the same height D above llondo. How would he speed of the rock a distance D54 above the surface compare to the answer you found above? a. It would be smaller. b. It would be bigger. c. It would he the same
