Question

A lift is desending with an acceleration 2m/sec2 what will be the aparent weight of a person of 80 kg mass​

Answer 1

ANSWER

Mass of man m=80 kg

Acceleration of the lift moving upwards a=5 m/s

2

Acceleration due to gravity g=10 m/s

2

Normal reaction acting on the man N=m(a+g)

∴ N=80(5+10)=1200 Newton
