Answer:
maximum speed of the elevator is 6.54 m/s
Explanation:
given,
force exerted on the elevator is 1.59 times passenger weight.
when the elevator accelerates upward with rate of a.
total force
F = m × (a+g)
1.59× mg = ma + mg
0.59 mg = ma
a = 0.59 g
we also have that
=
= 6.54 m/s
maximum speed of the elevator is 6.54 m/s
