This is a question i got, which i have NO CLUE how to solve, or what they are asking. Can I please get some help??
It reads:
The velocity of a body of mass m falling from rest under the action of gravity is given by the equation , where k is a constant that depends on the body's aerodynamic properties and the density of the air, g is the gravitational constant, and t is the number of seconds into the fall. Find the limiting velocity, , of a 340lb skydiver (mg = 340) when k=0.006.
Thanks, but there was one part that is confusing me a bit, i guess i am muddling the concepts of limits. How is it that if when t approaches so does and this results to ? I am just a bit confused here I guess... :s sorry for the late reply as well, i had some other assignments to do before completing this one, so i didn't get to focus much on this until now.
Thanks, but i understood that part. what i am not getting is how the limit as the expression tends to , the result is 1? I thought that for any integer, the so how is the answer 1? I am still confused.... i guess i am not sure how to treat limits of hyperbolic functions. (that trig function is pretty new to me, somehow i never got to learn it)
Thanks a lot for that. I never saw that calculation, we did limits of regular trig functions and other functions, but we came across hyperbolic functions by the way a long time after the fact, so we never got any detail on it... its still quite quite foreign to me. (i guess you didn't think you would've need to read and spell tht part huh?) But thanks a lot, much appreciated.
hello all
How can i find the coefficients is this equation: ?
I've tried expanding and then switching the sums but i didn't find the solution.
Thanks for any help.
