Answer :
The force, f, that the person exerts on the floor of the lift is 973.84 N.
Given that the lift is moving upwards, then its motion is against the force of gravity.
So that;
from the second equation of motion;
f = ma
we have;
f = mg - ma
since g > a
f = m(g - (-a))
= m(g + a)
m = 94 kg, a = 0.54 [tex]m/s^{2}[/tex], g = 9.82 [tex]m/s^{2}[/tex].
Then,
f = 94 (9.82 + 0.54)
= 973.84
f = 973.84 N
The force, f, the person exerts on the floor of the lift is 973.84 N.
