Solve the all parts of following problem given below:
Problem: The upward normal force exerted by the floor is 720N on an elevator passenger who weighs 770N.
Part A: What is the reaction force to the upward normal force exerted by the floor?
Part B: What is the reaction force to weight of the passenger? What is the direction of the acceleration?
I need help to find the reaction force to the upward normal force exerted by the floor.
