When the elevator is accelerating upwards, then the Effective weight of the Elevator becomes equal to the Tension in the supporting cable.
Tension = Effective weight of the Elevator = mass x (a + g)
where, a = upward acceleration & g = acceleration due to gravity
→ 29000 = 2000 ( a + g )
→ 14.5 = a + 9.8
→ a = 4.7 m/s²
∴ The upward acceleration is 4.7 m/s²
Hope it helps!!

If you take the acceleration due to gravity as 10 then, upward acceleration comes out as 4.5
