Use a system of equations to solve problem.Suppose that the position of a particle moving along a straight line is given by 
where t is time in seconds and a, b, and c are real numbers. If s(0) = 0.5, s(1) = 0.95, and s(2) = 1.8, find a, b, and c. Then find s(5).
A. a = -0.2, b = 0.25, c = 0.5; s(5) = 6.75
B. a = 0.2, b = 0.25, c = 0.5; s(5) = 6.75
C. a = 0.2, b = -0.25, c = 0.5; s(5) = 6.75
D. a = 0.2, b = 0.25, c = -0.5; s(5) = 6.75
