The answer is 80m.
You must go through all your "knowns" first. We know the following:
Fnet = 6000 N (centripedal force; Newton = kg*m/s^2)
m = 1200kg
v = 20m/s
Fnet = 6000 N
R = (m*v^2)/Fnet = 1200*400/6000 = 480,000/6000 = 80
R = 80m

If the speed is uniform than rigidity is: F = mass * ( speed^2/ radius) this implicate that R= mass*speed^2/rigidity . Now, out of your question, i'm no longer particular what's the speed ( 20m in line with ?) enable's assume that speed is 20 m/s, than we've: R= 12000*four hundred/6000 R= 800 m'

Fc = mv^2/r
6000 = (1200)(400)/r
r = 480000/6000
r = 80 m

80m
force = v^2/r
6000 newton = 1200*20^2/r
5 = 400/r
80 = r
