Σ/ε
σ = F/A
ε = ΔL/L
F = force
A = area
L = lenght
ΔL = |old lenght - new lenght|

Explanation:
minimum size of the mirror should be one half the person's height.
For this woman of 5 feet height, she would therefore need a mirror of length 2.5 feet
5ft ÷ 2 ft (half) = 2.5ft OR half of 5t is 2.5ft
Most likely gravity, because the gravity would pull it off course or wobble.
Kinetic energy would increase sir.
