A woman of mass 60 kg is standing in a lift at a shopping centre.
The lift is at rest.
The lift is at rest.?
State the value of the weight of the woman.
Calculate the force required to accelerate a mass of 60 kg at 2.5m/s².
The lift accelerates upwards at 2.5m/s².
Calculate the force exerted on the woman by the floor when the lift is accelerating.
The lift reaches a steady upward speed.
State the value of the force exerted on the woman by the floor at this steady
speed.

The weight of the woman is 588 newton because weight is a force which is equals to mass of the object multiply by gravity that is 9.8 meter per second square while on the other hand, the force of 150 newton is required to accelerate a mass of 60 kg at 2.5m/s².

Force required

We know that force is equals to mass multiply by acceleration so when we multiply a mass of 60 kg with 2.5m/s² acceleration we get 150 newton force so we can conclude that the weight of the woman is 588 newton and the force is 150 newton.
