ok its a science question. How much wouk would it take to lift a 1000kg limestone block 146m to the top of the Great Pyramid if W=Fd

omg i can't believe it the mass is 1000kg not the force!!omg
2006-11-14 12:19:34 · update #1
come on!!! i need to find the force!!! the force would be in ()N, not kg!!

ok, i'm in 7th grade science. i need to find the work. how do u keep getting 1000???!!!???!!!!! help
2006-11-14 12:23:38 · update #3
wut is the formula for gravity??
2006-11-14 12:24:54 · update #4
well, work and energy is about the same
so w = fd = mgh
m = 1000
g= 9.81 m/s^2
d = 146
w = 1000*9.81*146 (N/m)
plug it in there you go

W=FD, huh. You are so lucky I am in Physics!
D=146M right.
F=m(1000kg)XAcceleration
(gravity=9.8m/s)
F=1000X9.8=9800 this is the weight in Newtons
so far W=9,800 X 146
So your W is equal to 1,430,800J J= joules
Hope this helps

work=fd
so,work done=10000(146)
=1 460 000N
this is because force=ma
and in this case a is gravity whish is 10m/s2

w = f(d)
force = 1000 kg
d = 146 m
plug it in!

w=f(d)
w=?
f=1000kg
d=146m
sooo w=1000 x 146.... 146000 kg/m

W=force*distance
force=mass*acceleration
mass=1000kg
distance=146m
you need acceleration
acceleration=gravity=9.81m/s^2
force=1000kb*9.81m/s^2=9810Newtons
W=9810N*146m
W=1432260Joules
