Flaca has brought a bathroom scale with her in an elevator and is standing on it. Just before the elevator arrives at the top floor, as the car is slowing down, she notices that according to the scale, her weight appears to be off by 3% from its normal value W.

What is the magnitude of the acceleration of the elevator?

Expert Solution

Here the elevator is decelerating in upward direction(or accelerating in downwards direction).This means the person will observe lesser weight

Let the actual weight be mg and let deceleration be a

(mg-m(g-a))/mg = 0.03

a/g = 0.03

a=0.294 m/s²

Therefore, the deceleration of elevator in upward direction is 0.294 m/s²

A monkey sits on a bathroom scale which is on the floor of an elevator for a very tall building. The monkey has a mass of 42.0 kg. What is the reading on the scale if there is not motion and no acceleration? When the elevator starts moving the scale reads 480 N. Describe the acceleration for this case. At another time the scale reads 360 N. Describe the acceleration for this second case. Calculate the acceleration in each...

Astronauts in space cannot weigh themselves by standing on a bathroom scale. Instead, they determine their mass by oscillating on a large spring. Supppose an astronaut attaches one end of a large spring to her belt and the other end to a hook on the wall of the space capsule. A fellow astronaut then pulls her away from the wall and releases her. The spring's length as a function of time is shown in the figure below.

1. Florence, who weighs 560 N, stands on a bathroom scale in an elevator. What will she see the scale read when the elevator is accelerating upward at 5 m/s2?(g = 9.8 m/s2) Newtons 2.You swing a 3.41 kg bucket of water in a vertical circle of radius 0.900 m. At the top of the circle the speed of the bucket is 3.25 m/s. Find the tension in the rope tied to the bucket at the top of the circle

Consider a 80.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.36 m/s in 0.700 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.70 s and comes to rest. I can't seem to get the right answer on this one. Please help. Can someone show me the steps?
