Question

An elevator moves downwards with an acceleration of -5m/s2. The elevator and everything in it has a mass of 1000kg. What is the force of gravity on the elevator? What is the net force on the elevator? What is the force of tension holding up the elevator?

Answer 1

Fw = mg = 10,000 N

ΣF = ma = 5000 N

Ft + Fw = Σf ==> Ft = -5000 N
