sorry yes, radius of wheel is 1m, (2m diameter).
These both are hypothetical but potentially real questions with regards to vertical shaft mines. An elevator system if you like.
So, in the case of
1), 40 = F * 1 = 40N --> so it takes 40N of force to move it 1m/s ?
as for 2), if i can get...
if i remember right from high school physics, Ferro Magnetic means that it is easily magnetized. the domains in the metal align according to the magnet therefore becomming magnetic *i think*.
