In a particular Cartesian coordinate system, the y and z-components of the acceleration are zero and the x-component varies as given by the following function: ax(t) = 9t - 6t2 + 25e-t/F, where t is in seconds, ax is in meters per square second, and the constant F is in seconds. At t = 0, the particle was at position x = 7 m with a velocity pointing towards the positive x-axis and having magnitude 15 m/s. In the following problem you can take the constant F = 1.0 s.
