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 cant get the right answer to b, I keep getting the same velovity as V0 which cant 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!
