**Devron**, Wednesday, January 23, 2013 at 2:17amNot sure, but I'll take a crack at it since no one else answered the question. KE=Force of Friction * distance. 1/2(MV^2)=mg *U*d= 1/2[(69,990Kg)(9.86m/s)^2 =(69,990Kg) (9.8m/s^2) *(0.002) *d. Masses cancel out, so the equation should be written as 1/2(9.86m/s)^2=(9.8m/s^2)*(0.002)*d. Rearranging the equation, solve for d.
