1. if a 0.05kg coin is hanging from 22m above the ground:
a. If you drop it, how fast will the coin be moving halfway to the ground?
b. How fast will it be moving just before it hits the ground?
If you could point me the right direction with equations that would be great. I have a whole list of equations but I just don't see which ones I am supposed to you. Also, when the problem says "fast" that means velocity right?

a) KE= change in PE
1/2 m v^2= mg (22/2)
b) KE= change in PE
1/2 m v^2=mg(22)

Did you get 22/2 because it said halfway?
