A person of mass 60 kg is inside a lift of mass 940 kg and presses the button on control panel. The lift starts moving upwards with an acceleration 1.0 m/s2. If g510 ms22, calculate the tension in the supporting cable.

Question

jamesj · Answer

The tension provides the force that accelerates the lift.  What is that force?

2. the incremental force required to accelerate them upwards
