## SOLUTION This solution is FREE courtesy of BrainMass!

The sideways force is the centripetal force.
so F = mv^2/r (^2 is the square of v)
here the speed v = 160 km/hr = 160*1000 / 3600 (m/s) = 44.44 m/s

the radius of the cicular motion r = 600 m
then the centripetal force is
F = 70 * 44.44^2 / 600 = 230.45 N
so the sideways force is 230.45 N.
