1. The problem statement, all variables and given/known data A man 50.0kg has a terminal velocity of 42m/s. What value of D is required to make this possible? 2. Relevant equations V(terminal velocity) = (mg/D)^1/2 3. The attempt at a solution D = (50kg*9.8m/s^2)/(42m/s)^2) = 0.28kg/m The book's answer is 44kg/m. Is the book wrong or am I wrong?
