Question

A skydiver jumps out of a ;lane 3 km in the air and reaches terminal velocity after falling for 15 seconds. If he falls at a constant speed the rest of the way to the ground, how long will he have been in the air total?

Answer 1

I don't think it can be solved unless you consider what the friction was as it started to fall, it obviously was not falling that initial period at the rate of g.
