You are standing in a moving bus, facing forward, and you suddenly fall forward

Question

You are standing in a moving bus, facing forward, and you suddenly fall forward at the bus comes to an immediate stop. The force acting on you that causes you to fall forward is? No forces were acting on you to cause you to fall. The force of gravity The normal force due to your contact with the floor of the bus The force due to kinetic friction between you and the floor of the bus. The force due to kinetic friction between you and the floor of the bus Two forces, one with a magnitude of 3 N and the other with a magnitude of 5 N, are applied to an object. For which orientations of the forces shown in the diagrams is the magnitude of the acceleration of the object the least? IV V I II III A 90-kg man stands in an elevator that has a downward acceleration 2.2 ms^2. The force exerted by him on the floor is about: zero 1080 N 760 N 684 N 702 N A Ferris wheel has radius of 5 m and makes one revolution in 9 0 seconds A person weighing 670 N is sitting on one of the benches attached at the rim of the wheel. What is the apparent weight (that is, the normal force exerted on her by the bench) of the person as she passes through the lowest point of her motion? 503 N 1045 N 1210 N 460 N 837 N

Explanation / Answer

Q1.
The bus comes to a sudden halt which causes the person to fall forward. The reason why this happens is explained by Newton's First law of motion. An object at rest or moving at a constant velocity continues to do so unless it is acted upon by a force. When the person is moving in the bus the velocity of the person is constant. So there is no force that makes hom fall forward.
Option A.
