Answer:

Centrifugal Force = 45.65N

Step-by-step explanation:

Given the following data;

Mass, m = 80kg

Radius = 487m

Velocity = 60km/h to m/s = 60*1000/3600 = 16.67m/s

To find the centrifugal force;

Centrifugal Force = mv²/r

Substituting into the equation, we have;

Centrifugal Force = 80*16.67²/487

Centrifugal Force = 80*277.89/487

Centrifugal Force = 2223.12/487

Centrifugal Force = 45.65N
