Centripetal force is given by the equation,

#F=(mv^2)/r#

#m# is the mass of the object in kilograms

#v# is the velocity of the object in meters per second

#r# is the radius of curvature in meters

And so, we got:

#F=(80 \ "kg"*(21.3 \ "m/s")^2)/(7.2 \ "m")#

#=(80 \ "kg"*453.69 \ "m"^2"/s"^2)/(7.2 \ "m")#

#=5041 \ "kg m""/s"^2#

#=5041 \ "N"#
