Circular Motion Problem

The centripedal force is defined as the mass times the velocity squared divided by the radius of the loop.  The mass of the person is 55kg and her velocity she is traveling by is 65m/s while the radius of the loop is 380m when plugged into the formula the force is 612N.  612N is the force that is pushing the airplane out towards the rim of the loop.

The weight or gravity force is always and can be calculated by multiplying the mass of the women by the gravity force.  The centripetal force calculated before is bigger at 612N, because the centripetal is larger antoher force is therefore normal force.  Since the weight and centripetal forces should equal each other in order to keep the rider from being thrown off the plane.  The Fn is calculated using math skills.  Fa plus Fn must equal 612N. Fo equals 539N.  Using math Fn is found to be 73N.  This 73N force is most likely provided by a protector or harness or any other mechanism keeping the person strapped in.  This is balancing the forces.  The Fn is downward along with the weight force in order to create the state of equilibrium.

The woman is pushed out with 612N when it's greater than the persons weight force pull (539N) because of its greater force exerted outwards.  The person feels lighter than usual.

The Fl represents the normal force on the human.  The Fn or W is the weight force of the human while in the air.  The Fl arrow is straight up to counteract the weight force or Fn arrow.  The two forces need to unbalance or in this case be different because the human is in motion at the time.
