Question
After falling for 15.38 s a skydiver reaches terminal speed. If the skydiver is falling straight down, what is her acceleration?
Answers
Damon
same as the last question. At terminal speed which is constant velocity, no acceleration, the drag force up = the weight force ddown.

I am looking for an amount of pounds of air drag
Cameron Lawrence
or an amount of acceleration in pounds?
Damon
pounds of drag = weight = m g = mass in kg * 9.81 m/s^2 in Newtons
the acceleration is ZERO at terminal velocity.
the acceleration is ZERO at terminal velocity.
Damon
There is no such thing as acceleration in pounds
the weight in pounds = the drag in pounds if at terminal velocity.
the weight in pounds = the drag in pounds if at terminal velocity.

got it thanks!
