The lift is supported by a cable which is modelled as light and inextensible. The lift is moving upwards and decelerating at 1.8m.s⁻²
a) Find the tension in the lift cable. b) Find the magnitude of the normal reaction exerted by the floor of the lift on the person.
I have attempted this question, and got very close answers to the mark scheme, but I can't figure out why my answer is different.
The correct answers are:
(a) 5576 N (5 marks) (b) 656 N (4 marks)
The so-called correct answers seem to be obtained by taking the acceleration of gravity to be 10 m/sec$^2$ instead of 9.8 m/sec$^2$.
