A particle moves along the x-axis, its position at time t seconds given by s(t) = et - 2t meters. Positive values of s(t) indicate that the particle is to the right of x = 0, and negative values indicate that the particle is to the left of x = 0. (a) Calculate and interpret s(0), s'(0), and s"(0) in the context of this problem. Include the proper units with each answer. (b) At what time is the particle moving to the right at 4 meters per second?

A particle moves along the x-axis, its position at time t seconds given by s(t) = et - 2t meters. Positive
values of s(t) indicate that the particle is to the right of x = 0, and negative values indicate that the particle
is to the left of x = 0.
(a) Calculate and interpret s(0), s'(0), and s"(0) in the context of this problem. Include the proper units
with each answer.
