Homework Statement
Q 1. How fast will a skydiver be traveling 1 second after jumping from a plane?
Homework Equations
SUVAT formula
The Attempt at a Solution
[/B]
I guessed the answer to be 10 m/s because something to do with gravity and a 1 kg mass. The answer is correct according to the book but I’m not sure why. The mass of the skydiver will be much more than 1 kg. So my guess is not really an educated guess.
Please can you explain to me the answer in words terms (without the use of equations). (If possible) Thank you.I recently learned about the SUVAT formula from another post recently so have applied this here. (Please note that the book I’m reading does not even mention SUVAT formula yet so I don't think I meant to be using SUVAT)
s = distance
u = initial velocity
v = final velocity
a = acceleration
t = time
v = u + at
V = 0 + 10*1 (I am assuming acceleration to be 10m/s2 because of gravity)
V = 10m/s (The answer is correct according to the book)
I’d like to post the second part of this question here too, if I may because it is linked to the first question.Q 2. If the air resistance force on the skydiver is 0.1V2, what will be its magnitude and direction after one second?
Here I have no idea where to start. Please note this section of the book is discussing terminal velocity (if that has any relevance).
Answer in the book is 15 N upwards
