Using this given information can you help me understand how to find the Force exerted on the passengers seat at point B?

PATERSON GENERAL ROLLER COASTER DESIGN RE Refer to the drawing below of a proposed roller coaster design. Consider the 3 points - A, B, and C. The velocity of IS the roller coaster car at point A is 0 meters per second. Point A is 55 m above the ground, Point B is on the ground, and Point C is 40 meters above the ground. Assume the mass of the passenger is 60 kg. A Omls m= 60kg C H = 55m R = 20m B 26.
