Question

22. A fully loaded elevator car has a total mass of
1950 kg. If it rises 24 floors, a distance of 96 m in
15 s, calculate the potential energy of the car. take g=10ms-1​

Answer 1

Answer:

Given : m=6000 kg a=2 m/s

2g=10 m/s 2

Let the tension in the cable be T.

∴ ma=mg−T

⟹ T=m(g−a)=6000×(10−2)=4.8×10
