what provides the force on the person on the passenger seat?

The force on the person on the passenger seat that he experiences are normal force, downward force, and force of friction.What is Normal Force?The normal force is the force that surfaces use to prevent solid objects from piercing one another.Normal forces include contact forces. Two surfaces that are not in contact cannot be moved by a normal force. For example, if the surfaces of a table and a box are not in contact, they cannot apply the usual pressures to one another.When the person is sitting inside the car the downward force that is mg will act over there. Due to that downward force, a normal reaction force will also generate which will act normal in the direction of the downward force. One more force that will act is the static force of friction because the person is sitting in contact with the seat so the friction force is generated.To get more information about Normal Force :https://brainly.com/question/18799790#SPJ2

There's the acceleration of the car that provides a force and the normal force of the seat cushion which pushes upwards against the passenger
