The solution is,

However, is the reason why they don't do ##-0.5a_xt^2## because the negative of the acceleration has already taken care of itself?

Many thanks!

The answer seems to make
[tex]a_x=-\alpha_k (g+a)<0[/tex]
negative. You can make it positve one with your setting of ##-0.5a_xt^2##.

1. How does the student sliding bag along the floor in an elevator affect the elevator's motion?

Sliding a bag along the floor in an elevator does not affect the elevator's motion. The elevator's motion is determined by its motor and pulley system, not by the objects inside it.

2. Is it safe to slide a bag along the floor in an elevator?

Generally, it is safe to slide a bag along the floor in an elevator. However, it is important to make sure the bag is not too heavy or large, as it could potentially damage the elevator's floor or walls. It is also important to be mindful of other passengers and their belongings.

3. Can sliding a bag along the floor in an elevator cause damage to the elevator?

Sliding a bag along the floor in an elevator may cause minor scratches or scuffs on the elevator's floor or walls. However, as long as the bag is not too heavy or large, it should not cause any significant damage to the elevator.

4. Why do some elevators have signs prohibiting sliding objects along the floor?

Some elevators may have signs prohibiting sliding objects along the floor as a precautionary measure. While sliding a bag along the floor may not cause any damage, it could potentially lead to accidents or injuries if not done carefully.

5. What is the proper way to slide a bag along the floor in an elevator?

The proper way to slide a bag along the floor in an elevator is to make sure the bag is not too heavy or large, and to be mindful of other passengers and their belongings.
