## Homework Statement

Supposedly, I put an object on a scale inside the elevator of a building, the scale reads

*m1*. I start the elevator to the top of the building, during acceleration, the scale reads

*m2*. As the elevator normalized, the scale reads

*m1*. During the deceleration at the top, the scale reads

*m3*. The entire ride lasted

*t*seconds. I am asked to calculate the height of the building using this data.

## Homework Equations

I am not sure if these are all the equations i need:

v = (v0) + at

x = (x0) + (v0)t + (1/2)a(t^2)

(v^2) = (v0)^2 + 2a(x-(x0))

## The Attempt at a Solution

I have calculated the height of the building using trigonometry by using a protractor to find the angle from a point on the ground to the top of the building. Using that angle and a distance

*d*on the ground, I was able to find the height using

*tan θ = y/d*.

But I'm not sure how to use the scale data to get the height of the building.
