Free fall with air resistance (time and velocity) Calculator

Calculates the free fall time and velocity with air resistance from the free fall distance.

The default value of the air resistance coefficient, k=0.24(kg/m), assumes the value in skydiving.

    Purpose of use
    To find out how long the baby gorilla should have fallen from the trees in the Dora episode "Dora & Diego to the Rescue"

    Spoiler alert: that gorilla should be either dead or severely injured right now because it would've taken him between 2 and 7 seconds to fall depending on the height of those trees, and Dora, being the time-wasting brat she is, had to take precisely 18.793 seconds to catch him. Very disappointed with Dora's worth ethic right now. No wonder kids nowadays procrastinate so much!

    I'm writing a story in which the man punches a hole through an elevated freeway and then falls for four seconds, I wanna know how tall the freeway is.
