 Question 623704: The velocity v of an object t seconds after it has been dropped from a height above the surface of the earth is given by the equation v=32t feet per second, assuming no air resistance. If we assume that air resistance is proportional to the square of the velocity, then the velocity after t seconds is given by the following equation. v=100((e^.64t-1)/(e^.64t+1)) In how many seconds will the velocity be 50 feet per second? Getting the answer would be nice, but I would really appreciate an explanation as well. Thank you ! Click here to see answer by Alan3354(30993)
