1. The problem statement, all variables and given/known data Suppose that the velocity v(t) (in m/s) of a sky diver falling near the Earth's surface is given by the following exponential function, where time is measured in seconds. v(t) = 55 (1-e-0.18(t)) Find the initial velocity of the sky diver and the velocity after 6 seconds. Round your answers to the nearest whole number as necessary. 2. Relevant equations None. 3. The attempt at a solution I don't know what e is, so I can't even attempt this. And it's an online course with no book, just an online program we have to use for everything. It doesn't tell me what e is either.
