**jerry**, Wednesday, October 14, 2009 at 8:19pmchange in potential energy divided by the power. ( 1 W = 1 J/s)

Initial potential energy= mass* g* height

= mass * g*0

= 0

Final potential energy = mass* g* 16.0

finf diffence between final and initial and divide by Power. Answer will be in seconds(s)
