2. A HALO jumper with a mass of m parachutes from a gas balloon at time t = 0. Under certain assumptions, the distance, s(t), that he has fallen in time t is given by kt s( t) = 1:2 te ki/m - 1 for some positive constant k. (a) Find s'(0) and s"(0) and interpret the quantities in terms of the HALO jumper. (b) Relate the units of s'(t) and s"(t) to the units of t and s(t). 3. Find the linear approximation of the function g(x) = V1 + r at a =0 and use it to approximate the numbers V0.95 and V1.1. Illustrate by graphing g and the tangent line
