Question

A lift has an upward acceleration of 1.3 m/s. what force force will a man weighing 850 N exerts on the floor of the lift

Answer 1

Answer:

let's take g=10m/s^2

then, mass of the man will be,

m=850/10. {f=mg}

therefore, force on the floor

=m(g+a)

=85(10+6)

=1360N

please take the value of g as 9.8 for an accurate answer..

hope it helps..!
