Spiderman's cell phone falls from his pocket while he is surveying the city. His spider senses have
failed him. It takes the phone 3.6s to crash into the pavement below. How high up was Spiderman?

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
