If i could drop an anvil from the highest point in the sky (400 miles for general estimation im not sure what it is) but if i could do that how long would it take an anvil weighing 70 lbs to reach the surface?

im sorry 170 lbs not 70 lbs please add correction and it would hit flat ground not mountains or bottom of ocean

The atmosphere is only 60miles high, so if the anvil was dropped from 400miles, the I'm sure it would build enough speed that it would burn up once it reached the atmosphere. So it would never hit the ground.
Because we can assume that the anvil will be falling without any wind resistance for 340 miles of trip back to earth, we need to calculate how long it takes to travel that distance. 340 miles is 547,176 meters.
After graphing y=9.8x^2 I searched for y=547,176. The x value was roughly 236.28125. This means that it would take 3' 56.3" for the anvil to reach the atmosphere. Calculating dy/dx at time 236.3 I found the velocity around 10,354 mph!!! So now the question is weather or not the anvil will burn up in the atmosphere at that speed. Anvils are not very aerodynamic so my guess is yes. To give you an idea of how fast that is, the fastest jet travels at 6,700 mph. But it is aero dynamic and is designed to deal with the heat created by the friction of wind resistance. That said, I'm sorry to say, but if you dropped your anvil from such a distance, you would never see it again. It would be a show for thousands of people hundreds of miles away as we all observed the A.C.M.E. brand avil burn up in the atmosphere.

Depends entirely on the altitude of the land it falls on, but if you mean sea level, find out the distance of the highest point in the sky from sea level - consider this, that regardless of mass in the abscence of friction all objects fall towards the earth at 9.8 m/s2 - and continue to accelerate at that rate.

I would like to know who is going to take the time to bring an anvil up that high. I also think 400 mile is outside of earths gravitational pull so it wouldn't fall at all.

If you are posting this question in a math forum, you actually have to enclose some numbers, like how high, there is no rough guess at the height of the sky?
This also depends on wind resistance....try physics with a real number

dats y there r quadratic equations
exactly 45:03:7 4rm 400 miles

From 400 miles, it would take exactly 45:03.7

about the same amount of time it would take a man to eat a 50 pound block of cheese, and end up in pakistan with a squirrel in his brain.
so about 2 days

Long enough to get enough Speed/Strength / Potential to kill the poor guy setting Calculating the speed and watching it falling

depends if it landed on the top of mount everest or at the bottom of death valley.
I guess you probably mean sea level. hmm. Idon't know the answer. sorry
