Question
A person whose weight is 50.0 Newtons has an apparent weight of 45 Newtons on an elevator. Find the acceleration of the elevator and explain whether it is moving up or down. A person whose weight is 50.0 Newtons has an apparent weight of 45 Newtons on an elevator. Find the acceleration of the elevator and explain whether it is moving up or down. A person whose weight is 50.0 Newtons has an apparent weight of 45 Newtons on an elevator. Find the acceleration of the elevator and explain whether it is moving up or down.Explanation / Answer
here,
weight , W = 50 N
mass , m = W /g = 5.1 kg
the apparent weight , W' = 45 N
as the apparent weight is less than the real weight
the elevator is moving downward
let the accelration be a
W - W' = m * a
50 - 45 = 5.1 * a
solving for a
a= 0.98 m/s^2
the accelration of the elevator is 0.98 m/s^2
