The gravitational force in the downward direction is 20000 N and the tension force in the upward direction is 28000 N.
By newton's second law of motion, ΣF=ma
Net force, F = T – mg
ma = T – mg
2000 * a = 28000 – 20000 = 8000
ma = T – mg
2000 * a = 28000 – 20000 = 8000

To solve this problem, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration:
F = m * a
where F is the force, m is the mass, and a is the acceleration.
In this case, the force is the tension in the supporting cable, which is 28000 N, and the mass is 2000 kg. We can substitute these values into the equation and solve for the acceleration:
28000 N = 2000 kg * a
a = 28000 N / 2000 kg
a = 14 m/s^2
Therefore, the acceleration of the lift is 14 m/s^2.
F = m * a
where F is the force, m is the mass, and a is the acceleration.
In this case, the force is the tension in the supporting cable, which is 28000 N, and the mass is 2000 kg. We can substitute these values into the equation and solve for the acceleration:
28000 N = 2000 kg * a
a = 28000 N / 2000 kg
a = 14 m/s^2
Therefore, the acceleration of the lift is 14 m/s^2.
