A body of weight 80N stands in an elevator that is about to move,the force exalted on the floor in the body as the elevator move's upwards with acceleration of 5m is?
Answered by Chibuzor
The elevator move's upwards at a constant speed
Answered by R_scott
the acceleration force of the elevator is added to the gravitational force
... f = m a = (80 / g) * (g + 5)

when the elevator's speed is constant, the force is just the weight ... 80 N
