A- 625 N
B- 703 N
C- 15,625 N
D- 20,250 N

Centripetal Force can be found the following way....
mass x velocity^2 divided by the radius

x(t) = a million/2gt^2 t = 8 s, g = (approximately) 9.8 m/s^2 x(8) = 313.6 m (B) This makes a pair of assumptions: a million. The acceleration by way of gravity (g) is 9.8 m/s^2 (it surely varies counting on the place you're on earth). 2. there is not any air resistance (the stone is falling in a vacuum, in reality, air resistance might sluggish the falling of the stone fairly... although that is not any longer likely that the stone might attain terminal velocity in merely 8 seconds).
