Consider applying newton’s second law to a man riding an elevator (perhaps to calculate his acceleration). show answer incorrect answer which of the following forces must be considered? choose all that apply. the force that the man’s feet exert on the floor of the elevator the force of gravity on the elevator the force the elevator cable exerts on the elevator car the force that the man’s head exerts on his neck the force that the elevator floor exerts on the man’s feet the force of gravity on the man

The forces that must be considered to the scenario of a man riding an elevator with the aim of accelerating is:

According to Newton's second law, we can see that if there is an external force which acts on a body, then the rate of change of momentum is equal to the force.

As a result of this, we can see that from the scenario of the man in the elevator is applying a force to the elevator floor which in turn adds to the force of gravity and also acts on the elevator.

Therefore, the correct answers are options E and F

The force that the elevator floor exerts on the man’s feet

The force of gravity on the man

Explanation:

Only two force have to consider

1.  Force of gravity on the man

2. Force that the elevator floor exerts on the man's feet

When a man stands on the elevator floor then it apply a normal force on the floor of elevator.We know that from Newtons third law ,it states that every action have it same magnitude but opposite in direction reaction.

they should be similar or the same
