The maximum upward acceleration that the elevator can have without breaking is = 10.36m/s².
<h3>How to calculate maximum upward acceleration?</h3>To calculate the maximum acceleration of the elevator we must take into account Newton's second law and its formula that takes into account the following aspects:
- F = Is the force applied in newtons.
- m = Is the mass of the object in kilograms.
- a = Is the acceleration of the object in meters per second squeared.
- F = m × a
According to the above, we apply the values we have as follows:
- a =
- a =
- a = 10.36 m/s²

Answer:
reviewing the opinion of the two students we see that neither is right, since when the kinetic energy increases the potential energy decreases by the same value
Explanation:
For this exercise we must use the law of conservation of energy.
Starting point. Resting electron
Em₀ = U = eV
the potential difference and the electric field are related
V = - E d
Final point. When leaving the electric field
= K = ½ m v²
Em₀ = Em_{f}
e E d = ½ m v²
From this expression we see that when an electron moves from the initial point to the final point, the potential energy must decrease, for the total energy to be constant.
When reviewing the opinion of the two students we see that neither is right, since when the kinetic energy increases the potential energy decreases by the same value
