6. (7 points) A skydiver's position is given by $0.) and is accelerating at the rate :r\"(t). By Newton's second law, we can infer mm"(t) = a(t):s'(t), where a(t) = \"#1 is a function describing the air resistance and m = 2 is the skydiver's mass. (a) Find the general solution of this equation, for t 2 0. Hint: can you solve for U = 93' rst? (b) Find all solutions 16) satisfying 3(0) = 2000
