The centripetal force is calculated using the following rule:
F = (m * v^2) / r where
F is the centripetal force = 6000 newtons
m is the mass of the object = 1200 kg
v is the uniform velocity of the object = 20 m/sec
r is the radius of the circular curve that we want to calculate
Substitute with these givens in the above equation to get the radius as follows:
6000 = (1200 * (20)^2) / r
6000 = 480000 r
r = 80 meters
