A grandfather clock is powered by the descent of a 4.00 kg weight.(adsbygoogle = window.adsbygoogle || []).push({});

If the weight descends through a distance of 0.750 m in 3.00 days, how much power does it deliver to the clock?

I used my equations...

P=W/t

W=F*d

therefore P = (F*d)/t

F=m*a

m=4.00 kg

a=1.116x10^-11 ????

therefore F=4.465x10^-11 ????

d=.75 meters

t=259200 seconds

P= 1.292x10^-16 ???

This is obviously not right to me.... but on the force i know its net but where along the way do i find the net force accting upon the clock.... if i can figure out F in the equation then i will have the answer... help...
