Ok so I am working on this problem and can only get through the first question, the second question keeps stumping me.
I have uploaded the question along with my calculations for part a so you can see what I'm doing.
-----
A object of mass (m) is shot vertically up with V0 200 m/s.
Air resistance R is proportional with the square root of the velocity, R= -mkv^2
where k= 0.010m-1
a) How high does the object reach.
This one I have solved:
h= (1/2k) * ln [(g+kv^2)/g]
b)
What is the speed the object has when it hits the ground?
------
I just can't get the right answer to b, I keep getting the same velovity as V0 which can't be right.
IF it is possible to hand write your work or write it mathematically I would really appreciate it.
My work in attachment as both .pdf or .jpg, whatever you prefer.
In advance, thank you very much!
