Answer:
h= 63.5 m
Explanation:
- Assuming that air resistance is neglectable, and that the phone drops from Spiderman's pocket, we can use the following kinematic equation for the vertical displacement:
    [tex]\Delta h = \frac{1}2} * g* t^{2} = \frac{1}{2} *(-9.8 m/s2)*(3.6s)^{2} = -63.5 m[/tex]
- [tex]\Delta h = y - y{o} = -63.5 m[/tex]
- Taking as zero level reference the ground level, we get:
    y₀ = h = 63.5 m
