PHYSICS GRAVITY HELP!!?

Question

A certain white dwarf star was once an average star like our Sun. But now it is in the last stage of its evolution and is the size of our Moon but has the mass of our Sun. THE gravity on the surface on this star IS 4.38 * 10^7 m/s^2
 
A)  What would be the speed of a baseball dropped from a height of 2.0 m when it hit the surface?

easy!!
Vf=?
Vi=0
a=4.38*10^7
s=2m

2as= Vf^2 - Vi^2

=> Vf^2 = 2as = 2* 4.38*10^7 * 2 = 1.752^8

=> Vf=13236.314 m/s
